Fan from Palette to Palette

I was joining this great webinars in de Study Hall and when they were explaining fanning the following just popped up:
Wouldn't it be nice to have the abillity to use Fan together with selecting palettes?

You just select your fixtures, press Fan and now when you type: Color 1 thru Color 4 it just makes a fan from your first color palette to the 4th. Or from position to position, or from Intensity to Intensity etc.
