Anytime someone can use a full callsign and follow it up with a 3 digit
suffix, the APRStt server needs to be remembering the original to match
against for the shortcuts. That's the part that I was indicating a DB
(or lookup table or some-such) would be necessary and possibly a
challenge for resource-constrained platforms, especially if the
shortcuts are valid for 30 minutes or so.
