Say I have two PDFs with same/almost same content. The 2nd PDF is the revised one but page orders are different due to some reason. Now, if there was an option that compares the two files and rearranges the 2nd PDF's pages exactly like the 1st by comparing titles or line by line content, then I don't have to manually arrange it. It makes it easier to review.

Scenario 1 :
If the 2nd PDF has 'more' pages than the 1st (the content doesn't exist in 1st), then all pages but these extra pages should be rearranged and these pages should be moved to the end, so I can do it manually.

If the 2nd PDF has 'less' pages than the 1st, then it's not a problem. Follow the order of the pages by skipping.

Scenario 2:
If there are changes in the 2nd pdf, this tool/option should rearrange the pages by following the 'maximum' rule (match the contents to atleast 95%, if not 100%). Again, if there are extra pages, it should be moved to the end.
