Add-on Change cluster prefix in one click

[urivil]

Hi,
I'm looking for a plugin that does the following.
Administrators can click with one click in the cluster, without having to edit the first message, and one of the following prefixes will be applied: processed, for further processing, no processing is necessary.
Is it possible?

I would like to mention in favor of you @AndyB
who took one of his excellent plugins, and arranged in it all the functionality I asked for here.
