Can UE5 data layer support level instance inside the level instance?

Hello
The level instance function is working pretty well in the UE5 release version right now.
Except for one thing -
We are trying to use the level instance as same as the prefabs system - creating a level instance inside the level instance.
However, we found that level instance inside level instance can’t be added to the data layer.
Is it possible to support this function and it will be prefect.
Thanks!
