How do I create a color gradient across multiple multicell fixtures

We have a new Element 2 console that we are using in a TV studio. We use Elation sixbar 1000 fixtures that allow for us to access all twelve lights in the bar as a multicell patch. A fixture profile for the Sixbar 1000 is provided in EOS. We use these fixtures behind a transparent frosted wall to create a lighted cyc. I understand how to do an intensity change across multiple fixtures and I want to know if there was a similar way of doing that with color? We would like to set up a color gradient across six fixtures. For example blue on one end fading to yellow on the opposite end. Before I build a cue manually picking a color for each of the 72 cells I thought I would ask if there was an easier method.

I understand there is a color path tool that can be used with fades. Any chance that could be used to set a gradient across multiple fixtures?

Any help or ideas are appreciated.
