[aprssig] Another APRS hidden feature

This is a terrrific feature of my d700 and gpsmap276.  I had to move a
portable digipeater during a race event and on the way back from fetching
the digi, someone at the comm center plotted a point on the map where they
wanted me to place the portable digi at the other end of the course.  Worked
great!  All they had to do was plot it on the map and then call me by voice
to tell it it was there... I suppose entirely on aprs they could have txt
messaged the name of that waypoint to me so that I'd know to look for it.

In theory there is no difference between practice and theory.
