RCDroidBox/App and self made Gps

Hi,

using self made Vario and Gps will they be usable with RcDroidBox ?
The demo app shows in Database devices a list of existing devices:
MGPS Ex SN:000 Sensor 14
MVario Ex SN000 Sensor 4
that will not match self made ones.

In the DC/DS-16/24, in the Vario setup, it's possible to set which Ex Telemetry data is the vario, so open,
not stick to Jeti Vario.

Is it possible with RCDroidBox/App to setup which Ex Telemetry data is Gps Lon, Gps Lat, etc,
or it is restricted to an existing commercial list of sensors ?

Thanks.
