copy grade...i think

Hi everyone,
i'm really new on scratch ... and you will see ... lazy.
I'm trying to find the way to link multiple shot. Link, based on the TC or the reel name or manually or ...
For exemple if i have a shot who are present multiple time in the edit, the grade will be the same.
So when i grade the first one, the others will be updated.
And one more thing, if that existe can i adapte one shot without affecting the others?
it'like the Batch link on Davinci resolve or a concept based on Parent / child.
And if the are an automatic way (for ex. in the conform page)for starting i could be nice.
Thanks for your input
b
