I use a custom menu (based on inclusion and inclusion

I use a custom menu (based on inclusion and inclusion of page IDs) to link back to Product, Cart and Order Status pages. It works on the Store and Product Category Pages but not on the dynamically created Product Pages. Since these are dynamically created I have no Page IDs. How can this be resolved?
