I have data driven pages that have 10% overlap. I want to display the extent of the neighboring pages on each individual page but I don't want to show the entire page outline, just a corner or intersection. Is there a way I can do this efficiently without manually digitizing corners? there are cases where I have 40-50 pages and do not want to do them all by hand. I've attached a picture of what I'm talking about for reference. In the attached picture I want to display something similar to the black corners so that the user has an idea of how far the neighboring pages overlap.
