Analog triggers on PowerA Gamecube Controller Nintendont?

[AquaGreenBoi]

Is it possible to map analog triggers on a PowerA Gamecube Controller by making it so that holding the L button(not ZL) and pressing ZR at the same time does an analog input instead of a digital input or something like that. The controller ini files that I got from the internet doesnt have this function built in and I want to play Super Mario Sunshine properly. Is it possible to make a controller ini file that can make analog inputs possible on the PowerA Gamecube Controller by holding the L button(Not ZL) and pressing ZR or ZL at the same time? Like I said I want to play Super Mario Sunshine properly and official Gamecube controllers are expensive.
