Vista - Grouping radio buttons w/o group box

I'm trying to figure out how to use the old "start of group" concept
in MFC with my radio buttons so that I can have a matrix of them and
allow 1 selection per row. I don't want to use group boxes because I
want to save UI space.
For some reason I can't seem to figure out how to make this happen.
I'm presuming that there's a way to do it.

Hello IsRaEl,
You can put them in a Panel to get the same behaviour aswell. A panel doesn't
use up any space and should make it easier to make the grid look uniform.
