Is your feature request related to a problem? Please describe.
The MeshCore integration is currently not usable for me, as in Germany the majority of repeaters and companions are using the concept of regions resp. scopes. Messages without scopes are no longer forwarded by many repeaters here. Currently all messages in MeshMonitor are sent with the default scope configured on the companion via the official MeshCore app.

Describe the solution you'd like
I would like to be able to the following (just as in the official app):

• Discover regions from nearby repeaters
• Add scopes for every channel and a default scope for all messages which are sent without an explicit scope.
