Yes. Actually, you could just have one element in the list (parameter) that identifies 'targetGeom'. This would find 'targetGeom' anywhere, regardless of it's position in the hierarchy. You need the whole list (actor->channel->parameter) only if you specifically are looking for 'targetGeom's that below an 'actor->channel'. Attached is a new version that fixes a small bug I just found. I made a last minute change before my last posts and didn't notice it in my testing.
