Weakaura question/help

[jessica]

I want to create a simple thing, an indication of being rested, a "Zzz" icon, the same that blizzard shows on your unitframe, because I'm using an addon that changes all unitframes but it doesn't show the Zzz indication, I know its easy to spot an innkeeper or rested place if you logout quickly, but I just want that luxury of seeing the ZzZ icon indication, I just like it.

Can weakaura do that? thanks.
