How to create excepts or descriptions on this page, but not others?

I am trying to create a "catalog" on this page. I have several portfolios modules on the page. I would like to create an except or description in each project and then have it show on this page. I don't, however, want it to be displayed on the other pages with portfolios that have these same products and are in other product sections.

How do I get info descriptions on catalog, but not elsewhere?


I will send a snapshot of what I'm trying to do.
