Using 1 image for multiple associated products within a configurable product

Hi,
I am using your trial right now, and I am trying to figure out how I can associate or assign the same images to multiple simple products within a configurable product quickly.
Right now, I go to the configurable product, then click the associated products tab, and have been editing each one separately, but I want to do it more quickly.

The example is that I have say a zippered hooded sweatshirt with a design on it as the configurable product, and I have associated simple products for each size and color combination. Instead of editing each size and color, I would ideally select all and assign the same pictures to the white sizes, blue sizes, etc.

I hope this is possible.
Thanks
