I don't think so.  That would be the SSn-N extension to the WIDEn-N 
paradigm.  Pull up your favorite dog-eared copy of aprs101.pdf (or 
google to get a new one) and read up on "Message Groups" on pages 
72-73.  It is as Bob described, an APRS message receiving alias that 
causes the APRS client to display the incoming message as if it were 
directed to the receiving station.

The question, as I understood it, was getting a message group 
"callsign"'s APRS messages to gate from -IS to RF when there isn't 
really a "local" "recent" station using that "callsign".

Lynn (D) - KJ4ERJ - Now awaiting the clarification as well!
