Aye, ditch the "range" channel as an unchangable default. (leave it there as a selectable option for those that like to use it, but the rest of us would like to have the greater utility of being able to select precisely which two channels we are using). That way, for instance, unit members could tune, say, the squad channel and base, whilst their CO might tune the squad channel and the side-CO. Or members of a buff crew could set up a channel for themselves, plus one other... etc. etc.
