Airspeed ribbon in HUD, configurable AS/GS?

Anyone know if it is possible to configure the airspeed ribbon on the left of the HUD to be ground speed instead?

I see airspeed and groundspeed values below the ribbon, but not having an airspeed sensor I’d rather see the groundspeed.

by default is you dont have an AS sensor it will show GS.
ie
if as = 0 then tape = gs else tape = as
