Here is the official answer from my Garmin associate. He is about at
the top of the engineering food chain the

"Documented or not, I say what you are doing is fine.

We specifically designed the approach selection to do what you describe
because a pilot might learn on an ATIS frequency that he should expect a
particular approach/transition long before he's actually cleared for it.
So, the pilot can get ahead of the game by selecting the
approach/transition and placing it into the flight plan while still
navigating to the airport on his existing clearance. Then, once cleared
for the approach/transition, he can remove the airport from the flight
plan as you indicate, activate a direct-to the initial approach fix, or
whatever he is cleared to do to get established on the approach."

Thanks for looking into that Sam.
