Multiple Versions of one book in the same Format?
I came to Calibre to manage my ever growing collection of RPG ebooks, and after importing the first part of my collection I realized that there are a lot of books that would need to maintain several files of the same format (mostly pdf), some companies would separate the coverimage from the actual book to keep the actual book file smaller, and lost of companies provide a file for screen reading and another one for printing. I cant find a way to add e.g. 2 pdf files to one book, so I add all those files as individual books, but all the metadata is exactly the same and i would prefer a way to keep them organized as a singular book.
Would it be possible to add something like this via a plugin or is this something that would need a change in the actual application code?
