If the directory were built into a device that could control the radio
(e.g. a RPi with the database, a GPS, and some glue logic) then it
certainly could be a one button or even a zero button function.  I
understand the difficulty with obtaining the complete database from the
currently available offerings though perhaps having a method for
downloading data for a region and putting that into the in-car database
would work.[1]  Most people already do something similar for trip
planning so I don't think this would be too much of a stretch.

Barring that then using a cellular modem on the RPi would enable live
access to the online database instead of a locally maintained copy.
Slightly different glue logic but the same result applies.

[1] I also see that Rfinder will soon have databases installable on GPS
receivers like those from TomTom and Garmin.  A different kind of glue
logic could allow the GPS to flag when it finds itself within range of
one of the repeater waypoints and tune the radio accordingly if the data
is present within the waypoint metadata on the GPS receiver.
