Color correcting multiple materials at once? (Standard materials)

Hi,

I have a crapload of unique materials in my scene, and wish to go in and shift the hue/brightness/etc for a bunch of them. Some of them are are "multi/sub object" materials, others aren't.

I realize I can shift+drag the color correct map within the Slate Editor to copy it, then de-link the copy and apply it to another map, but I need to do this with so many materials that it would get really tedious.

Ideally, I'd have the ability to select several objects and then run a script that applies a color correction map to each diffuse map... WITH color correction settings. So, perhaps, enter a numerical value into a box for "hue shift" and have that be applied to each selected map.

If not, just having "blank" color correct slots applied would be good.

Perhaps a variation upon this script?

(I don't use Vray so that one doesn't work for me, but seems a promising start. Right now I'm using standard materials but may use Mental Ray in the future as well... but just requesting Standard to keep things simple.)

Many thanks in advance!
