I sometimes get an additional format of an existing book. Is there a way to add this new book to one that already exists in my library?
Example: I have a book already in in epub format in my library, but get another one in .mobi. I haven't yet checked out either for formatting or errors, so I'd like both before I decide which version I am going to keep. How do I add the 2nd one without deleting and then adding both at the same time.
