5D3 AF Point Selection (how to get it to show in rear LCD like on 7D)

No AF point selection option displayed on 5D3 when I press "Info" button.

7D shows AF point selection in the highlighted box.

On my 7D I get the AF point selection displayed when I press the "Info" button, but it doesn't come up on the 5D3 (top picture). I noticed there are a couple of blank squares on the 5D3 display; does anyone know if it's possible to assign that function to one of those blank spaces?

At the moment I have to press the Info button twice (first press brings up level), then press AF point selection button to get the rear LCD to display point selection window.

I hope I was able to convey what I'm trying to do. I'm still confused by the new Menu layout
