Is there a way to restrict the calibre metada search for a book to only the Kindle Store?
I ask this because the metadata search done by calibre seems to always choose the paperback version of the book and not the ebook version.

I would like to add the metadata from the kindle store only, that way I would have the correct isbn and ASIN numbers corresponding to the ebook format of the book and I believe that that would allow my Kindle Touch to display the correct cover of the book has well has the book description in the menu, wich at the moment don't work and I suspect it is because the isbn and asin associated to the books in the Kindle are the paperback ones.
