Whilst attempting to transcribe massive books such as the bible, it takes a fair bit of time to fill in the books (151 required for king james book). It would be amazing to line up a few books in your hotbar and have them all filled in. You would need to be able to select the starting book for copy pastes requiring more than 9 books.

Describe the solution you'd like
A method to fill in multiple books at a time. Ideally a hotbar's worth

Additional context
It would be mad to fill the entire bible in on randomn servers. Could bring true christianity to many minecraft servers

This isn't implemented quite yet, but some improvements have been made for this scenario with Textbook 1.1.0: The selected volume number is now remembered between books, and the location of the file you last imported is remembered.
