Allow drillthrough only to specific page

I have two different report pages and for each one I want to be able to drillthrough to a different page. They both drillthrough using the same dimension though. So when I right click, I get the option to drillthrough to both the report page which I want that page to drillthrough to and also the report page that other page is supposed to drillthrough to. Is it possible to make it so that each report page only drillsthrough to one of the pages with that dimension set as drillthrough?
