When adding books, I'd like an additional option:
Add Multiple books in a single directory, combine similar filenames into single book

What this would do is, given a flat directory with multiple books in various formats, is automatically consolidate duplicates in different formats, but still add multiple books for the non-duplicates.

Here's a use case where I hit this need:
Humble Book Bundles.
When I download my books from Humble, for simplicity, I just download all the book formats into the same directory.

This leaves me with a file structure like this:

book1.pdf
book1.mobi
book1.epub
book2.pdf
book2.mobi
book2.epub
book3.pdf
book3.mobi
book3.epub


I'd like all 9 of those books imported and consolidated into 3 books, each with 3 formats.
I've tried the import with duplicate detection, and it doesn't match all the duplicates correctly.

I'd prefer a simpler option that just said "if the base part of the filename is identical, assume all extensions match the same book" and import as such.
