Feature Req: Want add file name and location to score.

M4,W10. Tried the + and Text, nothing there for anything not score related. I like to save incremental changes, each with a different name, but once they are printed, I have a hard time telling what file they made from. Yes I know I could put in free text. but I would have to change that with every update, which is doable but error prone and forgettable. In Word and other word processing SW, you can enter a smart field that get updated when the file is saved under a different name. The pgm knows the filename and location, why can't that be a choice under + Text?

Newbie here, forgive me if the functionality is already there.
