Rigging Shadows of two drop zones

I created a generator in Motion 5 that has two Drop Zones that are angled 10 degrees towards each other. I want the drop zones to have shadows. I was able to create a Rig that controls all of the parameters of the shadow for one drop zone. Created a second Rig to control the parameters of the other Drop Zone but I don't see the rig once it is published. There is a shadow under the zone but I can't control it. Is it possible to do them individually? If I could control both shadows with one Rig that would be fine with me. The only difference in the shadows is that I want one to go to the left and the other to go to the right.

This post is kind of like the Bat Signal.... Ben will be along any second now, to make all things right in the world of Motion...
