The Lighting Controller

I cannot find instructions on how to remove/replace a fixture from an existing scene. I created scenes with older fixtures and I want to upgrade/replace with new fixtures that have more DMX channels. I do not want to completely re-write the scenes...just replace the fixtures with new and modify the scene accordingly. Please direct me to where to locate the scene editing instructions that cover this.
Thanks

Removing a light is fairly easy, just remove the fixture, it will remove it from the scene as well.

Replacing a light and not having to rewrite the scene is currently not possible.

In the future, this could be technical possible in V8, but this function has not been implemented yet.
Sorry for that.

+1 for this feature.
