ATC Frequency to stay on Unicom when Tower is active

When I’m at an airport which has an active Tower frequency but no ground frequency using Unicom will just keep switching me to tower frequency saying “Tower is active” in the notification bar. This is very annoying because I need to use Unicom to announce taxi or runway crossings yet the sim won’t let me stay on Unicom.

It would be great if the sim only changed you to tower automatically if you are airborne because that’s when you would need to be switched to tower from Unicom, but it shouldn’t automatically switch you while you are on the ground, maybe just notify you the first time. Even though this is a small problem it would make ground work a lot easier.
