Kangaroo2 drag / friction ?

Hi Daniel, is there a way in Kangaroo2 to reduce drag in between two colliding objects?

I'm pushing different objects into a mesh and I have issues with the mesh vertices sliding off the penetrating object. I tried all sorts of things and one compromise was to use AnchorXYZ for some points but that way I can only penetrate in Z axis.

So I'm looking for a custom goal to control drag...
