How to Backward cross reference in InDesign?

I have cross references within a book that refer to various appendicies in the back of the book. at the end of each appendix I want to list where they are mentioned in the body of the book. Is there a way to do this automatically? I understand I can find each cross reference in the book and create another cross reference from the appendicies to that reference. I'm hoping there is some way to do it automatically
