You can automate it if you're willing to break the "don't extract blank paragraphs in generated files" rule, and also perform a manual task once for each book.

* Create a new paragraph format named "blankline" and apply it to a new blank paragraph on last line of the the last page of the last file in the book.

* Include the paragraph format in the generated file definitions. Generate once, then on the generated file's reference pate, modify the paragraph format definition line so it contains only the <$paratext> building block.

* Regenerate, recognize the modified reference page. From now on, the generated files will contain the blank line IF it's been inserted on the last page of the book.
