Combing simulation studies having different fixture setups.

Hi,

Even though my study is not for a pressure vessel , I am aware that Solidworks pressure vessel analysis has an option of combining 2 studies but the prerequisite being that the 2 simulations should have same fixture arrangement. My goal is to find the resultant of the stress values found from the two analysis (with different fixtures) when combined.

Is there a feature/tool in solidworks which can allow me to do this?

Thanks!
