In designing many new student worksheets and their corresponding answer sheets, we frequently have to modify them. The problem then is there are mismatches, a student will hand in an older worksheet and we have a newer answer sheet to grade it against. What I want is a version number on each page in a document. So when that page is modified, its version number is increased as well.
Is there a way in Adobe InDesign to do this automatically? I don't care about the versioning scheme, only that we can check against the above kinds of mismatches.
