How do I select the simulation study my design study runs?

I have two static studies in a small assembly.  They have different geometries.  I created the first study and then a design study for it.  Then I created the second (static) study and ran the design study, but I don't know which static study the design study solved for.  The geometries are very similar so the results I get from the second time I ran the design study on what I thought was the second static study should-be/are very similar to the first time I ran the design study when only the first static study existed.  So I can't tell if the second time I ran the design study it was solving for the first static study or second.
