Just my thought. Could this possibly be merged with the existing mention tag expression? I feel like it makes more sense to be added to the already existing mention tag expression since you could technically do set {_x} to mention tag of slash command named "x" with id which is very similar to doing set {_x} to mention tag of member with id "0000" in guild with id "0000". Maybe @ItsTheSky has a similar or different input about this?

Yeah, I had the same thought when I made it, but I feel like it's too complicated to add it to the current tag expression, since the input are relatively different. But I'm gonna take a look at that if it is possible or not.

Now I think of it, shouldn't we also introduce slash command-related properties? not only its mention type, but also its (numerical) ID, maybe state and values?
If that's the case, its mention tag would be merged into the common mention tag expression yes.
