Bookmarking custom template pages which all have the same page ID
I have a custom page I created in WP which displays different real estate listings. Since it is a custom page the page ID is always the same.
For example both of these URLs display different properties but both have the Page Id of 11.

I want to add a bookmarking plugin to give users the ability to save listings to their favorites. I have installed just about every plugin available and they all operate the same way by adding to your favorites via page ID.
Is there a way to give custom pages unique page IDs or is there a way to use a different ID to save a page?
