It would be good to be able to switch to using COM2 radio from COM1 'on the fly'. Some of my a/c have a glitch (inherited from FS9, not innate to the plane itself apparently) whereby if the flight isn't set up properly via the default c172, COM1 radio dials don't work (the PSS 757 and 777 for instance).
Obviously, I try to remember to set up the flight so that the COM1 radio will work, but it doesn't always work/happen and since in those cases the COM2 dials are always operational, it'd be good to be able to switch to using COM2 instead of COM1 whilst in flight.
Thanks
