Using both Roomie and Pioneer AVNavigator12

I can’t seem to switch between Roomie and the Pioneer AVNavigator12 app. If I start one before the other, the other one doesn’t connect. I’m assuming there is a timeout period to open the port for new connections. I noticed the Pioneer SC-1222-K has up to 4 ports that you can define, one being the default of 23. Is there a way to configure Roomie to use another port something line 48023? Or is there a way to make each app disconnect more quickly to free up the receiver?

If you add the device via Manual IP, you can specify any port for Roomie to use for that device.
