You could use a callback on the transform from the hand to update the transform on the other node. The other way is to position the other node under the hand in the hierarchy. The transforms of the other node then become relative to the hand. You'd need to convert local to world in order to do updates in the world frame but your goal of co-movement would be achieved.
