Interaction tag , joints animation and reset PSR

Hello everyone,
I’m experimenting with the interaction tag in r16
using it to drive joint rotations.

Interaction tag works fine with pose morphs but how about using to drive joints?

A) How do I set auto key to work with interaction tag without having to select the joint?
B) How to reset PSR on the joint directly from the interaction tag, without having to select for the joint?
C) How to activate the interaction tag’s polygons through a subdivision cage?
I’ve seen this done in demo’s bu they don’t describe the set-up… :/

Any ideas?

Thanks!
