Need to accomplish something similar to how RI would cascade updates, inserts and deletes. I'm not sure how to do that in FPD

Each account can have multiple properties. Each page would duplicate borrower information name, such as name and account number but the property information would change. What is the best way to keep track of the number of pages? How do I keep track of where each page is in the order? My main concern is when deleting or adding. If I hardcode a page number into each page then I have to go back and edit each affected page.
