Is your feature request related to a problem?

When using a 3-axis stick, like the FrSKY 3-axis Gimbal , on RadioMaster TX16 and plug it in to SI (EXT1 in EdgeTX) the rotation direction is reversed to what one would expect. Since this is an hall-effect pot, the wires can't be reversed.
This can of course be compensated for in Mixer or Output of the models, but I would like it to be reversed at the hardware level so that calibration and vertical sliders are moving in the correct direction as well.

Describe the solution you'd like

Ability to individually invert the EXT1 and EXT2 pots in the Hardware menu.
