How to Trigger Level Sequence in a Level Instance from the Parent Level?

I am trying to implement a system using Level Instances in Unreal Engine.

I have Level B, which contains a Level Sequence to animate specific actors. I want to bring Level B into Level A as a Level Instance. Then, I want to control and trigger the Level Sequence from Level A’s Level Sequence.

Is there an efficient way to achieve this? Any guidance or examples would be greatly appreciated!

Hello! Hopefully I’m understanding your question correctly, just to be safe you basically want to be able to trigger a sequence that lives in level A(for example, persistent) with something that exists on another level (for example gameplay).
If thats the case maybe this how-to guide will help you: Play Cinematics from Blueprints in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community

You should also be able to do this just by adding the level sequence asset to the other level. If you use spawnables, it should just work. If you use possessables, the object names will need to match. Or, you can rebind the possessables at runtime.

Here’s a doc on rebinding:

Hopefully at least one of these options will help you achieve what you are trying to do

First of all, thank you for your answer.

But I think my explanation was a bit lacking.
I use Unreal for graphic rendering, not game development.
The reason I asked this question is
I am looking for an efficient way to merge levels made by several team members into one level.
I use CinemaForD to import assets and animations into Unreal and compose the level.
When I pass this to someone else and copy the actors from my level and paste them into the level made by my team member, all the items in the sequencer are missing.
That is why I want the level instance and sequencer to work properly without missing.
I hope my explanation is understandable.
