Auto updating Table of Contents

In Indesign, I'm creating a furniture catalog that has a table of contents with every page listed. Every year, this catalog gets updated and some of the pages shuffle.  Is there a way to drop in a special character for page number on the table of contents that is linked to its own page? You can add a page number, but from what I can see, it has to be the current page, the next page, the previous page or a section marker. If I could link the marker to a specific page, I wouldn't have to update the page multiple times before sending to print.
