We create large multi page InDesign files of a range of packaging. Each page requires the date created on it, which is fine the first time we output all the files but every now and then we have to go back in to amend and re-output individual pages. This means when we try to use Text Variables > Modification Date the variable changes on every page even if we have only altered 1 out of the 80 pages.
We need the date to stay the same on the un-modified pages so that we can see when it was last worked on. Is there a way to limit the modification date to a page by page basis?
Offhand, I think the easiest way would be to have each of your pages as a separate document, and use an InDesign book to link them.
This doesn't really work for us as we have the main base design of the packaging on a master page so that if something needs amending we only have to do it once, rather than 80 separate times in each individual InDesign file.
That's the beauty of using the InDesign Book feature. You can sync master pages between all documents in the Book. So, amend the master page in one document designated as the source, then select all the documents in the book panel and synchronize.
It's a couple of extra steps, but it doesn't required having to rework each document separately.
