Yes it's possible.
You can adjust the channels in the menu (I can't remember exactly from where). You just assign the knob on that specific channel. Lets sya say you assign the knob to channel 8.
If you are using MK electronics, in MK Tools you go to Channels tab and assign that channel to a poti. Lets say poti 2.
And at the camera tab, you can assign Poti2 for tilt control.
