Possible to see AGL height during flight?

[Phantogram]

Is it possible ( maybe via modded freeflight version) to see the AGL drone height during flight, instead of / besides of the relative height vs starting point?
This would be useful for me in hilly terrain..

The drone or FF6 is not terrain or ground aware - so it would be impossible to determine AGL.

The only height data measured by the drone is GPS based altitude..

The log files do have product above ground height entry - but that is a measurement of height above take-off point.

Is it GPS based altitude?
Or is it, like on DJI, a startoff altitude of "0", and changes after are only barometer changes?
