Setting a switched output to change between specific us values

[breadoven]

Is there any way to set up a switched mixer input to toggle between 2 specific pwm us values, e.g. 0/1, 0/2, 0/4. 0/8 ... 0/256 etc, such that a number of switches can be used to multiplex on a single channel which can be decoded by firmware such as INAV etc. The intention being to allow multiple switch inputs (up to 10 ?) to be carried by a single channel. It's possible to do it using percentages since that's what the radio is set to at the moment. If the radio was set to show pwm us values instead by reflashing would that allow the mixer to work in pwm us values down to 1 us ?

Or is there anything in the EdgeTx pipeline that will auto configure switch multiplexing on a single channel ?
