4.27 Remotw Web API- how to access Blueprint properties?

The new WebRemote API in 4.27 is awesome! However can’t figure out how I would expose Blueprint properties to the API.

Everything is only exposed in the editor at the instance level.

I have a Spotlight wrapped in a Blueprint actor. And then many of these instanced in my scene.

I can expose the properties for individual Spotlights but not for the actual Blueprint.

ie I only want one glabal setting for Light Intensity, Volumetric Fog, Color, etc
