It appears we may be getting a new role in Meshtastic called CLIENT_BASE. It acts as a ROUTER for favorited nodes such as your personal T-Decks, T1000-E, MeshPocket, etc but acts as a standard CLIENT otherwise.
You would put the CLIENT_BASE node in your attic, on your flagpole, or on your roof and set your personal nodes as favorites. That way a weak 3rd party CLIENT with low SNR does not take priority over your much better positioned high node.
The OP in this github issue had a node on his house that wasn't getting utilized because another client in somebody else's house farther away was getting the signal weaker and rebroadcasting it first.

Edit: its out. Upgrade your well-positioned node to version 2.7.9 and upgrade your app to version 2.7.0-open.0
Then simply favorite your portable devices from your well-positioned node.
2.7.9 has been released so I believe it has it because it says the pull request was merged a week ago. At least as of now the app is not showing it as an option so it might only be available if you use the command line
Then again, I am running app version 2.6.34, so it might be showing up in the newer versions and I'm just not aware of it. There is a 2.7.0-open.0 that's out, but I'm not using it right now.
