Independent Gamepad Stick Sensitivity Adjustment

I play on PC with an XSX controller. It appears the X/Y sensitivity only affects the right stick, or only substantially. The left stick movements are too slow and leads to fatigue in the right hand fairly quickly. Add a way to independently adjust the X/Y sensitivity on the left stick or adjust it to a greater degree when adjusting the X/Y sensitivity settings. Making the right faster and faster doesn't solve the problem and bring the two sticks into synergy where they work comfortably together.
