@Grins:
As an alternative design, the "Book Awards" section of this post may be of interest to you:
https://www.mobileread.com/forums/sho...d.php?t=261712
One of its attachments has a table of 4,532 books with each book's multiple awards, and ready to be imported into Calibre.
See the attached example for Larry Niven.
If it is worth it to you, with a little extra work you could append the year of the award to the award name. Or not.
