How do you make a line trace only come from one controller with VR template?

Obviously in the VR template one hand is mirrored to give you the two hands. When I attach a line trace to the MotionController blueprint it appears on both hands. Can someone please talk me through a way to get it working only on the one hand, so I can teleport with one hand and line-trace interact with the other.

Never mind, solved. I attached a “Switch on EControllerHand” before the line trace. Seems to work.
