In Custom, you should be able to type numbers in the boxes, or move the sliders to achieve this.
With the temperature numeric field active, you can even use the arrow keys to move one way or other in steps of 50 (or 500 if you hold down the shift key while 'arrowing').
Same goes for Tint, but I think it goes in steps of 1 or 10 (as the numbers are much smaller).
