Analog/D-Pad switch wiring

Hi, how would someone go about wiring up a switch to swap between D-Pad and left Analog stick on a Sixaxis? Is this even possible? I know the sticks have two pots with variable resistance, so they’d need a resister to make them “digital,” but where would the solder points be for those? Or can you not solder since the pots are basically a range of off to on and whatever is in between, so there is no real Up or Down solder points?
