Is there a plugin that categorizes templates?

One of annoying things about Siteorigin is that there is no option to have categories of templates that I can see.

Is there a way to achieve this? A plugin perhaps?

I had a brief look at code and It would have to be a new button I think as some funtionality is in Javascript so couldn’t achieve everything with filters so would involve forking the existing code behind a new button.

If nothing exists I may take it on as a project.
