Duplicate Multiple Books?

I often want to duplicate book records, and just type up the differences, instead of creating new book records and typing everything all over again.

* Files may represent different versions of the same book

* Separate chapters

* Different editions

* Different translations

I can't see any way to set up a keyboard shortcut to duplicate each book. I have to go through a dialogue to duplicate each book, again and again and again. I can't select multiple books, and go through the dialogue once to create 1 duplicate of 2 or 10 or more selected books.

Is there some trick I've missed this time?
