Allow multiple or combined inputs that include addon / additional functions.

Problem

Currently multi-button inputs only allow “base buttons”, such ad RT+LT, as requested in #575

Now that with the pin settings of for many add-ons and additional functions moved to the main Pin Settings page of the web configurator, it would be great to allow multi inputs including these functions too, such as Macro1+LB.

I’m not asking for multi inputs that will “lock” the pin, such as Pin Settings for the peripherals, but only those inputs that should be set on the Pin Settings page, such as Function, Macro, Turbo, Tilt etc.

Understood that there may be edge cases where, for e.g., having Turbo+B1 on the same key causes issue, but I am not requesting any fool-proof mechanism at the moment, since whoever uses such multi inputs should be aware of the consequences themselves.

Do you plan to work on this feature yourself?

Unfortunately it is beyond my capability as I’m not sure if it needs some system-level overhaul.

Start by tracing the multi-button input handling and the Pin Settings handling in the firmware and web configurator. Determine how base buttons are currently allowed, then assess support for Function, Macro, Turbo, and Tilt combinations while excluding peripheral settings that lock a pin. Done means combinations such as Macro1+LB can be configured and used without requiring fool-proof conflict handling.
