Color Correct Material?

[simmsimaging]

I just realized how useful it would be to have a version of the Color Correction (or Color Correct for the old die-hards) that affected an entire material, and not just a shader. I want to make colour variants of a material that derives it's overall colour from some pretty complicated blending of maps etc. To alter it is a real pain doing it on the sub-material level.

Anyone know of a good workaround or plugin that can colour shift the output of a whole material?
