Is there a way to delete remote view tags very fast?

[AnriMachishiro]

We know there are many improvements about remote view tags since 2.0. Now we can copy & paste & move them very fast.
And since the current experimental 2.0.37 version, there are more virtual signals looks like box drawing characters, which fit the remote view tag using too. We can use them to draw box in the remote view, to reserve some areas for further developments.
But... After actually using the reserved area, how can I delete those tons of tags in my remote view? Is there a hotkey like copying/pasting/moving the tags too?

Thanks for any reply in advance.
