Does anyone know if it is possible to change what the steering wheel controls do? For example, on my previous cars ( 2006 A4 and 2008 A4 ) I used to be able to change the radio/sirius station by just going up or down on the left wheel. Scroll up, the channel is changed to the next station automatically.

I can sort of do that on my 2011 A4, I can scroll up or down, but then I have to press it to select the station. I just want it to jump to the next station without having to press it in.
