Why can't you use LandscapeProxies in Data Layers

Hey guys, I have a question.
So I have a scene where I want the player to be able to see the entire landscape I’ve built. But with the new World Partition system, it unloads chunks I want to be visible. I tried adding the unloaded chunks to a data layer and tried to load them at runtime, it didn’t work. Then I tried just to unload a single chunk at runtime and Data Layers will not change the Landscape Streaming Proxies Status (unloaded, loaded, active)

Is there a work around for this. Why isn’t this a feature in World Partition being able to load landscapes manually?
