3-Point Hitch retrofit with position control 3ph on GC series

[LuckyP62]

I'm new to the tractor world and recently purchased a GC2410. Amazing what the little beast can accomplish! My biggest challenge is the 3PH control. I have a long drive and run a box blade quite often. IT is a royal PITA adjusting the box with the 3PH valve on the GC - Not sure if this is possible (or feasible) but has anyone retrofitted a position control valve on their GC?
