Lightchanel's: Tell a light what objects it does effect in runtime

Is it possible to set a light to only affect dynamic objects at runtime (not those marked as static)?

The UDK has a feature for this which is called "lightchanels". See this link for reference.

This would allow me to set up a dedicated shadow light which would only affect dynamic objects, and not the objects marked as static. This would reduce my amount of shadow caster objects at runtime.

None of the current lightmapping solutions (also not dual lightmapping) would allow this, as far as i can see. But it would be nice to use only your lightmapped shadows for static objects and then add shadows for dynamic objects to the scene. The Performance could benefit dramatically from this option.
