Is there an existing issue for this feature request?

I have searched the existing issues

In the cooling section there are options for part auxiliary and Exhaust fans however these are hardcoded to P2/P3.

Which printers will be beneficial to this feature?

Klipper

Describe the solution you'd like

To be able to choose the fan index for Auxiliary/Exhaust fan, even better we could define the gcode i.e. use the SET_FAN_SPEED macro.

Describe alternatives you've considered

There is a solution to fix this in Klipper with a custom macro but I feel it would be better if the user could choose what fan is assigned to what pin/setting, rather than it be arbitrary.

Additional context

No response
