Separate Opacity and Marking Randomizer

Not sure if this has been brought up before, but:

Make it possible to randomize the marking, but not the opacity.

I'd love love love to be able to go to the Customizer, set everything to 100% and press randomize and get a lovely 10 mark, 100% result rather than have to press "randomize" and then fix the opacities repeatedly. As someone who likes to use Randomize to find a base to work from when designing wolves, this would be a life-saver!

Essentially it's just adding a dice to the marking slot tier and swap the one on the right (next to opacity) to only affect opacity.

Sounds useful for playing with randomization, support.
