Arrival space management#1608

Good morning, I’d like to report the following problems I’ve encountered:
1 - Often, when approaching, it doesn’t let you contact the approach unit, tower, or ground. Especially if you change procedures.
2 - When selecting another radio from the cockpit, it doesn’t pick up the frequency (e.g., radio number 2).
3 - When you call the incoming ground for a taxi to the parking lot, ATC assigns you the gate, not you.
4 - It would be nice to be able to choose which procedures ATC assigns you, for example, having a table of all the procedures and runways at an airport, and flagging a list that ATC could assign you.
I hope I’ve helped highlight any anomalies.
