Then you lose the device identifier, and complicate the algorithm.  I don't
think the added size will be a big deal - transmit with just AUTO, and it
gets replaced by WIDE1-1, and you're still using 1 slot.  I guess you might
want ID turned on, so it'd be more like AUTO => N1VG-10*,WIDE1-1.  Even if
you put the AUTO in the destination field, it's still going to take up the
same space once it's digi'd.
