Within the new color mode, use scroll wheel to control adjustments

From what I can see so far, I think the new Color Mode within Premiere Beta has some awesome features that will make color grading easier, but the controls are a little bit difficult to use.  Keeping the existing controls, it would be great if users could also hover over each color control wheel and use the middle mouse scroll wheel to adjust them.  For bidirectional controls, regular scrolling could adjust vertically and scroll + shift could adjust horizontally.
