Adjustable Heading on In-Flight Setup

On former versions of Flight Simulator, you could adjust your heading when
setting up an in-flight ‘flight’. So if you were setting up an approach to an
airport, or wish to start out at a particular heading, you could adjust your
planes direction. I would like to ask if we could get that nice option back.
It was a great feature for setting up for practice landings, also setting up
for a flight in a tight Alps flight in a valley. You might head into a wall of
mountains if you cannot adjust heading before launching the flight. Bill

I’m bumping this suggestion. Not only would this provide convenience for
regular users, but having the ability to set heading (and altitude!) when
setting up a flight would be wonderful during the development and testing
