Use Trackball as an Intensity Wheel

Road Hog 4.21

Could we please have the option to use the Kensington trackball (north / south movement) as an intensity wheel. This is an option on other desks I use and is very useful for fine control of intensity when you're constantly fine tweaking levels as we do in the TV world constantly. Personally I never use the trackball for pan and tilt anyway and so this woud be a very welcome addition.

Thank you.
