How to know at runtime Actor is in a DataLayer

Hello,
It’s seems DataLayers are the best new way to sort actors in a world/level.
So I wanted to avoid duplicate this meta information in tags (or gameplay tags), and use only data layers.
But I don’t find a way to know at runtime if an Actor is in a DataLayer, and then do thing accordingly.
Is there a way to do that, or will it be in the future, or should we duplicate this information in data layers and tags (for example for an interactables/climbing zones types)?
