Sort A-Z, Z-A and Variable

Appreciate this has been covered a few times but  to flag up the issue again;

I find it incredibly odd that you can sort A-Z / Large to Small but you can't do the reverse, there are a lot of situations whereby the reverse is required and we've eneded up having to create calculated metrics with a negative symbol in front in order to allow us to sort correctly.

Aside from that it's somewhat frustrating you can sort by any metric but not by the variable itself.
