Gimbal Control with Joystick + QGroundControl

I currently have a Pixhawk1 running the latest PX4 1.10 firmware and I’m struggling to figure out how to control a camera gimbal via Logitec gamepad buttons. I have an old school tarot 2 axis GoPro gimbal that I’m trying to manually control the tilt/pitch on via the gamepad so I can maintain manual control via telemetry for long range flights.

Please let me know if anyone has figured out how to successfully do this!!
