Request: Gamepad Axis and Button controls for Ball Controller.

With the new Ball controller functions, it would be a great option to be able to add gamepad controller axis and button functions to enable Ball Controller and to control and move the ball.

This can allow a user to play and test a table with a gamepad, and then enable ball controller with a button, then move the ball around as needed with a thumbstick anywhere you want, then disable ball controller to resume normal play at anytime without the need to touch a mouse or keyboard.

This is especially handy when testing on a cabinet or in VR in the future.
