Taking the Honeycomb Bravo to the next level - advanced configs

Not sure if you can provide some insight,

I’m currently trying to figure out how to assign a single bravo toggle to rotate between the COM1 and COM2 (ref Multiple Logitech Flight Radio Panel compatibility). As noted within that posting, I went into the control settings thinking that by assigning one of bravo toggle switches, I could end having it change between COM1 (toggle state up) or COM2 (toggle state down), no current need for the other rotated states as usually found on the KMA-28

Sadly this didn’t do anything, and as far I currently know, the only means is the soft switch option (under atc) to swap COM1 and COM2 as active. I have mapped the the Bravo annunciator lights, but it’s more of a monitor flag state instead of a “new input type not already configured”.

Any recommendations on if there is a keyboard shortcut to toggle or how the xml was coded for the custom input (on the bravo side)?
