Is there a way to set heading hold and throttle hold in the AeroFly Pro software. I can't find any indication of it in the manual or in any search of this forum

Want to work on autos but need throttle hold. Could "get by" without heading hold but would like to have it.

So far also have not been able to change throttle curve. It is set in "v" curve, which has not been a problem, but would like to change it somewhat also.

Any help is appreciated.
