Is It possible to disable Pawn collision with certain Physics assets colliders


I am setting the Physics Asset for this giant insect model. He has very skinny legs, so I’d like to know if there is any way to disable Pawn collision only in the legs bones, so Pawns can interact with the rag doll, but ignore small colliders (sort of like the “Large Chunk Threshold” option in destructible mesh).

How can I achieve that?
