xsi5 : Find parameter being controlled by custom parameter?

I'm trying to figure out how a slider in a custom parameter set is causing some objects to rotate. I've checked all the objects and can't find any expressions or other indications on the objects of what the custom parameter is linked to. So, my question is, it there a way to see what is being controlled by a custom parameter similar to the way you can see what is constrained or being controlled by an expression in the schematic view?

This isn't extremely important at this time because I have a tutorial at home that explains what is going on, but I was just wondering if it is possible to get to this information.

Thanks!
