Enabling Text for Mana (Player frame)

[deculo]

I was wondering if there was any way to show my mana in numbers on the player frames. I'd prefer it within the mana bar, but I'm not sure if that's possible. It does display health at the top of the frame already (i.e: 17,637/22,190). Is it possible for my mana to show up in that same way as well somewhere in the frame?
