Custom dial settings for aperture and color temperature

[eco_bach1]

Hi
Can anyone help with the following?
I want to set my rotary dial(around the set button) to dial in color temperature and

My shutter dial to change aperture

These 2 custom settings would be ideal for shooting video but haven't been able to figure out how to do this...

Unless I am missing something there doesn't seem to be a way to easily change aperture without diving into the ML submenus.
On my 7D the aperture is easily changed with the rotary dial(around the set button)
