Tristate CheckBoxes as labels for GroupBox elements in MFC dialog

I am working on this popup dialog and I am at the design stage:

I have three tristate checkboxes at the top and three group boxes with 4 checkboxes in each. The concept is simple:

• If all 4 check boxes are ticked then the master checkbox is ticked.
• If none of them are ticked then the master one is untickd.
• If only 1 to 3 of them are ticked then the master one is set to intermediatery.

The user will be able to tick the master check box to bulk switch on all off all the associated checkboxes.

My question relates to the 3 static group boxes. I want those three lables changed into the 3 tri-state checkboxes as it will look nicer. When I played with WPF i had full control over how the labels looked for groupboxes but whatabout here in a MFC project?
