Having just implement Hub Mesh I thought how helpful it would be to get a filtered device list by adding a control along the top with the ability to limit display to All Devices (Default) Local Devices Only Hub Mesh Devices Only
You can do a search of 'Linked' which will give you the devices that are 'imported' from another hub.
You can also search 'user' or 'system' which will give you devices using built-in drivers or user drivers.
I'm not saying your request is not a valid one but just saying that there are searches already available that can narrow things down for you.
