Additive control rig

Is it possible to use the control rig as an additive layer to an existing animation? I tried long and hard and having an animation track anywhere near it makes the control rig controls disappear.

This is what i’m searching too. I dont undestand why they dont delivery that yet. this is just the firtst thing that any animator will need at first glance.
If you find please, let me know. I’ll do the same.
