UE5 - How to automatically add new assets to selected Data Layer and manually trigger them with Blueprints?

Ok, I know the auto-functionality of World Partition, but Level Streaming is broken in UE5

I’m testing the data layers, but I cant add new assets to the viewport and add them to the selected active data layer… the only way to automatically add those assets is manually selecting them in the viewport and then:

But If I keep adding assets from the Content Browser to the viewport, they are always added to my first layer even if that layer is not visible or unchecked… very frustrating… I mean in UE5 If I’m building a castle with rocks I would have to select manually each rock and then move them to the data layer, while levels in UE4 just auto added each new asset to the active layer… OMG please help, I’m confused.

Also, I’m not sure how to trigger this data layers from a Blueprint, and I need to do that, because If I have secret areas in the project, I want to reveal them, not by proximity but by activating someting, but not sure how to trigger those Data layers from a Blueprint

Please help
