Hi all!
I'm searching for a way to password protect a set of markups on a pdf without disabling the ability for other users to add new markups without the password.
A working example would be one user, a drawing checker in this case, would go through the pdf creating markups. When they're complete, they lock the file so those markups cannot be tampered with. Then, a different user would open the same pdf and add a new set of markups to acknowledge and record their progress working through the checker's markups, without the ability to modify those original markups.
Does anyone have any ideas on how to accomplish this?
