How to open multiple scenegraph

My understanding is that the easiest way to handle different "logical" scenes in the current implementation of RSG is not to create multiple custom components inheriting from Scene - but instead to have only 1 Scene and under it attach different non-scene components representing your different logical screens. You can either add/remove said screens from the scene or you can have them all attached but hide/show the "slide" that is currently needed by the app flow.
