Soft Credits in Analytics

Hi All, 

I'm building a dashboard to display the historical giving by FY of a group we consider to be our Major Donors. I have three donors whose giving is through partial or full soft credit. Two of these individuals have a separate charitable trust I can include in the values filter I built to isolate the Major Donors.  One of these donors has soft credits through a community foundation that many of our patrons utilize in their giving. If I isolate by the community foundation's constituent id, I would be pulling in the gift records of 20+ individuals who are not designated as our Major Donors. 

Any ideas or tricks for pulling in a soft credit? 

Thanks!
