Pan and Tilt Sliders for MTCP, Designer 2

Does anyone know of a way, or has tried to create a set of sliders for pan and tilt of a fixture? I would imagine one could grab the variable of the slider, then output the value to a DMX address. Another option would be to use the color picker and just grab the X, and Y variables, then send them to a different address. Better yet, is there a P/T control (like the color picker) that I am just missing? The over all idea is an end user would be easily able to re-position a fixture without having to create a new scene.
