NMEA data output does not include weather data

Via the RJ12 connection, the Uranus exports NMEA GPS data. The webpage specifically mentions that this is compatible with 10Micron mounts.
I've just tried to establish this connection (you have to make your own cable), and it works. As soon as Uranus has a GPS fix, the 10Micron mount responds very quickly with a GPS sync.
But... the NMEA data output only includes GPS data, no weather data. The 10Micron mounts work with an internal pointing model, which depends on refraction data. And for this refraction data it needs air pressure and temperature.
The alternative (and mainstream) solution is the MG(P)Box from Astromi.ch. I had hoped that the Uranus could be used as an alternative, but it can't. With only GPS data, that output is of no great use to 10Micron users.
Pegasus Astro, will you be able to change this via a firmware update?
