copy color grade to group

I color graded a clip instead of a group.
How can i copy that color grade to the whole group?

Grab a still, reset the clip grade, apply the still grade to the Group.

i'm kind of desperately hijacking this thread i want to know how to combine two separate mask to show the same background.

i want to add a power window mask on the second lens, i know it has to do with the combination of a key mixer and parallel node but i'm not too sure how to work it
thanks in advance to anybody who can answer this question for me

I think it would be really simple:
Color -> Window -> Curve (on the top)
then you select Curve on the bottom and you can draw your new window
