Is it not possible to assign a default color, an input color and an input preview color to the same button?

I've tried, and can get the default and An input, or preview. I've also tried without a default color, but can't get preview and active activators on the same button.

On my launchpad, I'm using a scene per pad, and am using triggers to set the next scene up in preview, and I'd like to see the reflected to show ready on the launchpad as well. Activating the "preview" button will send it to active.

Thanks for that Richard!
I would suspect anytime an input is in the active program, that that activator would have priority, and you can only have one input as Preview at a time. The only time this would be an issue is when the input is in both the active and preview positions, and then again as stated above, the program would have priority, as that is your live output.
