I'm sure it could be done by hand, but the general method would be
to code that format into the APRS client itself so that the human
operator didn't have to worry about it.  Just turn on the "higher
resolution" togglebutton and the packet gets formatted for transmit
with the extra pieces on the end.  Those clients that understood the
extra pieces would show a higher resolution position, those that
didn't would show the position as if the extra pieces weren't
present.
