Is there a way to make an actor's Light components light ONLY the other components of the actor they are parented to?

I have 4 scenes I want to display in my game. They are basically Actors with several Staticmesh or Plane components and lit with PointLight components.
They are all relatively close to each other, for the sake of a central camera that can turn to look at each scene. Currently any given scene’s PointLight components light up a neighboring scene, which gives undesirable lighting for each scene.
I know about Light Channels, but there only seems to be 3 available? Is there a way to make an actor’s Light components light ONLY the other components of the actor they are parented to?
