Is there a way, to save the Light, after the setup, like we can do it with the Materials?

Once the setup for Sky, Sun, grouping etc .. is all done, it would be handy, to be able to save it for a later usage again.

Just like we can do it with the materials already. You set them up and save 'em. Once needed again, you just load them into the script again. That's a great feature.

Would that be possible with Lights, as well?
