Mapping jog wheel to Studio One 6

Hi All,
I have got the KLE mk3 working great with Studio One 6, the only thing I am missing is mapping the main encoder/jog wheel to scroll through which ever menu is active, perhaps up and down main tracks or the instruments or effects lists is that’s where the window focus lies.
Any tips would be great, I have tried playing around with the mode the wheel functions in using the Arturia midi controller editing software but I still can see what function I need to map to.

Thanks all.
