It should be possible to automatically apply a scene (or constituent elements, like a background image) to every other scene. This is simply to avoid a situation where the intended scene elements die and OBS simply streams nothing, or worse, unintended screen area.
Currently it is necessary to create a scene for this purpose, and then manually add it as a source to every other scene, which is barely better than manually adding the image itself to every scene. It is only saving you work in the event that you change the image selection and want it to propagate automatically.
