Renaming sets for cross hotbar

Is this possible at all? I did some searching around, looked at a commands list...can't find anything.

I decided to go back to controller from M+KB and I thought to myself HMMM it would be nice if I could change Set 1 to "Single Target" and perhaps Set 2 to "AoE" or something along those lines.

Something like this:

Good idea? Bad idea? Also, if it were to say "Change to name" instead of "Change Set" when holding down R1. Maybe even showing the set name where 1 through 8 are. Thoughts?

It's not possible but it would be a good idea.

Currently, that kind of feature doesn't exist.

Sounds like a nice idea but I bet it's not going to be simple task for this one, need to consider the text length, make sure it's takes in all language characters + the SET is actually an image and not a font I think, so they would need to replace that part with text with similar font. Etc...

Might be possible to have an alias show up on chatlog or something but dunno if that's going to be good for anyone. /alias SET1 "Single Target" > when you switch to SET1 it displayed XHB switched to "Single Target" in chat log.
