Describe the feature
Right clicking on a linked P2P bus to access some kind of "frequency settings gui", in that gui you could set a name for the frequency that could show up in WAILA/TOP when looking at it or a name hovering over the bus when looking at it, specify what kind of p2p bus (Yes, I know you can right click with stuff too to set the type) and other things that might be useful.

Maybe even add a "P2P Terminal" that will group buses in a list after each frequency, were each p2p bus would appear and you could hover over to see the coordinates to that specific bus.

Reasons why it should be considered
It's a feature that I and I think many others would agree should be implemented, it would almost be a final touch to the new frequency colouring on the p2p buses. It will help organize the buses even more.

That is already supported by vanilla itself.

What about the p2p terminal @yueh?
