Set attributes for multiple clips at once

There is another topic like this earlier in the thread. TC yes you could change those attributes like that but what about effects? I'm not talking about just adding effects but changing them. Right now if I do an Ultra Key to a sequence and then edit the video and end up making 15-20 small cuts into several clips, if I make a change to the Ultra Key that I missed earlier than I end up having to delete and copy paste all those small little clips. I'd rather just select all of them and make the edit once.

To a certain extent, that can be done assuming all the clips are coming from the same source (for example a really long interview that is all one take). Under the Effect Controls tab or Lumetri Color, simply make changes to Master instead of the sequence name. That will adjust all instances of that clip in the timeline.
