Interface to tagging qubes?

Is there a way to tag individual qubes from the GUI? It seems like something that would be under “Qube Settings”, but i don’t see it.

(I’m talking about the type of tag that can be used in policies)

AFAIK it’s not implemented, however I could not find a specific issue in the issue tracker. Related: Improve UX of management functionality when renaming VMs · Issue #5184 · QubesOS/qubes-issues · GitHub
and Support for user-created groups of VMs · Issue #6679 · QubesOS/qubes-issues · GitHub.

There’s only qvm-tags right now (so, only CLI, no GUI yet). A GUI frontend has been discussed.
