Pixel mapping Dimmers

Hi all, With the advent of LED Blinders and the such, I keep running into applications where I would want to put them in a pixel map layer. Something such as a 7x7 or a cuepix WW4. Anyone have any luck in creating a work around to make this happen? I have played with the fixture builder to overlap color and intensity on the same channel but still doesn't seem to work. Help would be appreciated.
