I'm looking to set my "C2" slot for shooting while panning, so I've made a few tweaks and saved it to C2. However one thing I'd like do is change what function the rear dial drives on my G6. I'd like to make it so that the real dial controls shutter speed (it currently controls aperture). Does anybody know how to make it so that the dial will control shutter speed instead of aperture, in a way so that I can save it to my C2 settings? Thank you!
