Duplicating Groups?

Hello, I'm trying to make a profile that makes each individual key cycle through a rainbow on touch (just a single key at a time). However after creating a group, and assigning the gradient of my choice, how can I duplicate the group so I can assign multiple copy's to individual keys? Is there a way I can copy the gradient rainbow to another blank group I create? Thank you!

You dont need to do any of this. there is a function called type lighting, next to any mode click the 3 bar hamburger tab and click reactive lighting. This actually made me lol hard.
