XY color wheel controls on encoders

XY is quickly becoming prevalent in the film world.  It's not as complicated as many forum posts seem to make it: just meter the light, use our built in XY to adjust to the XY you are trying to match, record CP.  The issue is being quick and precise with 4 digits of precision with the current slider setup.  Encoder access would speed this up greatly and again reinforce the need for a hardware console.
