Maybe I've missed something in the settings, or discovered a glitch, but is there some way to save a Point Light?  After I create a point light, if I change the scene, it deletes it.  If I go back to the scene the point light was originally created with, it isn't there.  This is extremely frustrating, as I'm trying to keep the point light, regardless of scene, to simulate an LED light source.  I'd really not like to have to set up a new point light for every single scene I'm testing out.
