How do I define a load that rotates from 0deg to 360deg from the original position in Creo?

Hello everyone,

I would like to simulate the stress vs. load angle in Creo. Instead of creating individual load set for every 20 degree, I would like to see if there is a way to define the load with the parameter relation, and make Creo run the analysis for with a new load for every 20 degree. 

The load magnitude will stay the same, but the direction will change. Thank you so much!
