Physics asset, add bones?

Hello! How do you get access to the bones of the skeleton in the physics asset editor that are currently not in use?

I.E if I wanted to add constraints to the fingers of the existing mannequin without regenerating the entire thing.

Aaaaah, there’s the option I’ve been looking for. Thank you!

As a follow-up, is it possible to constrain multiple bones to the same body?
I wish to lock all the bones in the hands to the hand body/constraint so they don’t dangle freely.

Or do I have to manage bones and constraints for every single bone individually?

So if they don’t have bodies, they just inherit motion from the parent bone?

be careful with the inertial blending below or any setting that targets the whole chain.
they will force the bones to behave as you tell them even if they have no constraints.
