Add 'groups' in 'Renaming methods' column?

I dont know if I have ever asked about this before, but if I have, I wanna ask again :)
Do you think it would be helpful to add the ability to create groups of renaming methods so that the group(s) can be turned off/on as a whole? I think that all it would require would be to add a '+' before the existing '+' to account for groups/folders of methods.

An enhancement to that would also be to have the ability to name the groups the same as we can name the single methods.

It seems to me that this would be a 'useful for everyone' thing instead of a 'just useful for me' thing.

Or, is there ALREADY a way to accomplish the same thing that I am missing??
