Is it possible to program the C1 and C2 buttons on the back of the controller, (when using a single controller) to control gimbal yaw on C1 and Gimbal reset on C2. I have tried a number of times and only see this in the "master/slave" section of the controller and gimbal portion of the pilot app and nothing I have done seems to make the buttons usable. If it can be done, I would appreciate a quick tutorial. Thanks
