Sure, as long as the content of the different files is exactly the same. Please upload the ePub file. After you have completed your checkout please email the other files to support@bookbaby.com. Be sure to name the files so we can tell what you want us to do. If the content in those files is different (ex. there's audio for Apple Books, color images vs. grayscale, hyperlinks vs. no hyperlinks) those are different books, and should be signed up separately.
