How do I edit the material of enscape Assets? Especially Lights

Hi,

I've been playing around with enscape recently and loving it so far.

In Chaos Cosmos, there is an option to merge the assets with the vray material editor. And then we get access to the materials of those chaos cosmos assets.

Unfortunately, I didn't find this option in enscape.

Is it possible to adjust the materials of enscape assets such as downlights?
I would like to make it emissive and show up in the renders.

Yes, but I don't get access to the material since it is part of enscape asset library.
