How to stop Calibre from downloading tags from Amazon?

[razorsoup]

The Amazon.com metadata plugin does not have a tags checkbox in the configuration options to allow me to stop using tags from Amazon. If a match from a source I do want tags from is found Calibre uses those but if the only match is from Amazon it insists on using the tags from there. Is there any way to instruct Calibre to discard tag data from Amazon.com?

On November 22, 1963, three shots rang out in Dallas, President Kennedy died, and the world changed. What if you could change it back? Stephen King’s heart-stoppingly dramatic new novel is about a man who travels back in time to prevent the JFK assassination—a thousand page tour de force. 
Following his massively successful novel Under the Dome, King sweeps readers back in time to another moment—a real life moment—when everything went wrong: the JFK assassination. And he introduces readers to a character who has the power to change the course of history. 
Jake Epping is a thirty-five-year-old high school English teacher in Lisbon Falls, Maine, who makes extra money teaching adults in the GED program. He receives an essay from one of the students—a gruesome, harrowing first person story about the night 50 years ago when Harry Dunning’s father came home and killed his mother, his sister, and his brother with a hammer. Harry escaped with a smashed leg, as evidenced by his crooked walk. 
Not much later, Jake’s friend Al, who runs the local diner, divulges a secret: his storeroom is a portal to 1958. He enlists Jake on an insane—and insanely possible—mission to try to prevent the Kennedy assassination. So begins Jake’s new life as George Amberson and his new world of Elvis and JFK, of big American cars and sock hops, of a troubled loner named Lee Harvey Oswald and a beautiful high school librarian named Sadie Dunhill, who becomes the love of Jake’s life – a life that transgresses all the normal rules of time. 
A tribute to a simpler era and a devastating exercise in escalating suspense, 11/22/63 is Stephen King at his epic best.
Review
Fine stories to take with us into the night. Neil Gaiman on FULL DARK, NO STARS in the Guardian America's greatest living novelist. Lee Child King's gift of storytelling is unrivalled. His ferocious imagination is unlimited. George Pelecanos 'King's most purely entertaining novel in years ... utterly compelling.' John Connolly on UNDER THE DOME 'Staggeringly addictive.' USA Today on UNDER THE DOME 'Tight and energetic from start to finish.' New York Times on UNDER THE DOME 'The pedal is indeed to the metal.' Guardian on UNDER THE DOME Delivers a lot of praise and enjoy. The story comes off the blocks with almost alarming speed ... he tells a story like a pro ... 11.22.63 kept me up all night. Daily Telegraph Stephen King at his epic, pedal-to-metal best' Alison Flood, Sunday Times, Culture not just an accomplished time-travel yarn but an action-heavy meditation on chance, choice and fate. Independent Books of the Year The details of Fifties America, the cars, the clothes, the food, the televisions with wonky horizontal hold, are so vivid that you begin to wonder whether the author himself hasn't had access to a time machine. ...But as you worry at the paradoxes and the brilliantly explained pseudo science there is no denying that this monster yearn is blindingly impressive. Manly writers run out of steam as they get older. King, though, writes books that are ever longer and more demanding. I can't wait to see what he will tackle next. Daily Express Stephen King's new novel, 11.22.63, combines a variety of genres, being a JFK assassination, a story of time travel, a variation on the grail quest, a novel of voyeurism, a love story, a historical novel, a counter-factual historical novel and the chilling tale of a sinister animate universe, a form which can be traced back to the ghost stories of MR James. London Revuew of Books The master of the pen has written yet another extraordinary novel. The Independent Perhaps only seasoned storyteller Stephen King could accomplish changing the course of history in his vast time-travelling masterpiece whilst effortlessly weaving political and social details with abundant humour. King's intriguing new story structure will surely catapult the author to another best-seller. The Australian Women's Weekly These early sections of the novel are almost irresistible entertaining, enlivened not just by King's supreme control of the form but by his sardonic wit and usual generosity of spirit and expansiveness. Yet as Jack/George moves closer to his goal, other, darker notes intrude, as time itself begins to resist his attempts to change its course, and as he begins to identify with his quarry... Beneath the reassuring glow of King's portrait of an earlier, simpler time moves a darker and less comfortable vision, a glimpse of the terrifying machinery that moves below the surface of human history, and which stands as a stark, chilling rejoinder to the fantasies of escape embodied in so many time travel stories. The Weekend Australia Mammoth but entertaining, this is part sci-fi, part suspense and part travelogue of a long-ago America. Who Weekly Stephen King is a remarkable and wonderful storyteller who never loosens his grip on the reader throughout the 750-page book. Women's Day The novel is big, ambitious and haunting. King has probably absorbed the social, political, and popular culture of his baby-boom American generation as thoroughly and imaginatively as any other writer. Mildura Midweek King weaves the social, political and popular culture of his baby-boom American generation into a devastating exercise in escalating suspense. Daily Liberal A fascinating journey. Armidale Express Extra A delightful blend of history and fantasy by a man who has always had a soft spot for an America where men wore fedoras, drove big Fords and could do the foxtrot. A thriller by a genius writer. The Courier Mail People often complain there are no writers of the stature of Dickens anymore. I think that for pure energy and invention missed with compassion, King stands in that writer's direct line. Dickens' heir is alive and well and living in Maine. Eureka Street This is Stephen King in top and chilling form. Take 5 You have to take a leap of faith with time-travel novels, but if there's one writer who can pull it off, it's Stephen King. ... Captivating, surprisingly pacy and free from sci-fi cliche, it's no wonder the film version is already being planned. Shortlist The most remarkable story-teller in modern American literature. Mark Lawson Guardian a powerful love story Mirror One of the strengths of the book is King's at once nostalgic and honest view of the end of the Eisenhower era. King manages to avoid both sentimentalizing the past and treating it with massive condescension; his role as the poet of American brand-names serves him well here. Independent King swiftly moves beyond vintage Americana to unfold a stunningly panoramic portrait of the era. His [King's] fascination with evil...arranges characters among clear mortal frontiers that fell meaningful rather than simplistic. King commands an inordinately fat space on the bookshelf with 11.22.63 but it's hard to begrudge when his vast imagination is working across such an epic canvas. Seven, The Sunday Telegraph 11.22.63 marks a definite maturing of literary command and ambition. The key to any novel set in an alternate reality is credible world building, the steady accumulation of detail - preferably lightly distributed - that brings the story alive. King succeeds in this, partly drawing from his own memories. Adam LeBor, FT Weekend ...This is the American of Stephen King's childhood and it's one that he re-creates in vivid and loving detail... This is a truly compulsive, addictive novel not just about time-travel or the Kennedy assassination but about recent American history and its might-have-beens, about love, and about how life 'turns on a dime'. It's a thunking 700-pager which left me only wanting more. The master storyteller in truly masterful form. Daily Mail 
Review
'The reader feels the benefit of 40 years of narrative craftsmanship and reflection on his nation's history. Going backwards proves to be another step forward for the most remarkable storyteller in modern American literature.' -- Mark Lawson, Guardian 'The pages of 11.22.63 fly by, filled with immediacy, pathos and suspense. It takes great brazenness to go anywhere near this subject matter. But it takes great skill to make this story even remotely credible. Mr. King makes it all look easy, which is surely his book's fanciest trick.' -- New York Times 'A wonderful book: page-turningly exciting, witty, wise, melancholic. But also utterly human, profoundly decent' -- Ashley Pharoah, co-writer and co-creator of Life on Mars and Ashes to Ashes 'Take King's hand and allow him to lead you into a past so vibrant and complete that you can almost taste it. But hold on tight, the Master of Horror has now become the Master of Time ... Utterly enthralling, emotional and magical' -- Matthew Graham, co-writer and co-creator of Life on Mars and Ashes to Ashes 'Fine stories to take with us into the night.' -- Neil Gaiman in the Guardian 'America's greatest living novelist.' -- Lee Child 'King's gift of storytelling is unrivalled.

It creates a world you can lose yourself in.' -- Peter Robinson in the Sunday Express 20111118 'He writes incomparably good stories ... King's mastery of plot and his ability to create characters and situations both homespun and far-fetched means that this is the book you dream of getting stuck on the train home with.' -- Independent on Sunday 20111118 'The story moves seamlessly from detailed reality to elaborate fantasy and back again through a meticulously researched backdrop of late 1950s events, fashion and sentimentality. It is a story of temptation, sacrifice, politics, love and self-interest. It was enthralling and I loved it.' -- Townsville Bulletin (Australia) 20111118 'The fictional offering that engaged me most urgently ... an extraordinarily ambitious tale.' -- Canberra City News 20111118 'A suspenseful drama.' -- New Idea (Australia 20111118 'Time travel and an incredible talent for storytelling combine to produce a unique tour de force.' -- Sun 20111118 'A book of the year.' -- Sun 20111118 'Cleverly evokes the moral dilemmas of time travel and whether a time traveller could or should prevent the assassination of John F.

The download of tags from amazon is very rare, it happens only for a few books that in my experience, which is why there is no filtering for tags. But I can easily add it in the next release.
