Reply To: Is it possible to automate text changes on individual page headers and footers?

So a script would look for all instances of the character style, add a vertical bar in the margin at the whole range of the character style, and increment the revision number. The only problem with this is that when you apply a character style to a range of text, any character styles already applied to that range will be overridden.

Your specs are very specific, so a script like that is unlikely to exist, but it shouldn’t be particularly complicated.
