Program to remap BT headset volume buttons?
 

Does anyone know of a program that will let me remap what the buttons (volume) on my BT headset control? I would like them to control the up and down on my phones D pad.

The reason I ask is that I have a few old headsets laying around and I am curious to see if i can use one to control my Touch Pro when using TV out. All I need are the up/down (which in portrait are right/left) to control powerpoint and picture viewer.
