On my old controller I used to have a map to control 3 effects at once with the wet/dry knob. The mapping I used is here

I've just upgraded to an S4MK2 and X1MK2 from a Denon MC3000 and I was wondering if there is a way to do this in the default mapping or if anyone knows of a mapping which can do the same thing or even show me how to do it?
