How to duplicate a sequencer while detach animation asset?

Hello, I have a level sequence and i used it to make an animation asset of a shoot. they are linked.

How do i Duplicate this sequence, but detach it from the animation asset so i can make another animation inside it, so this new animation will be linked to it instead?

I prefer not open a new sequencer because i will have to redo all the parenting and assigning. its kinda tedious
