Can I group multiple objects as one prefab?

Hi there… So I was dressing a scene with what i thought were prefabbed models, and now I need to prefab all my objects, but I have duplicates in the scene. So I have to redress the whole scene. Is there a way to group my duplicate objects as one prefab? Or at least an easier way to do this other than redress my entire scene?

Create a prefab in your project hierarchy, Highlight all objects in the scene, drag them to the prefab you created, rename prefab, delete all objects in scene(maybe minus the camera in the scene and associating with the prefab).

Then if you use that prefab all the things will appear from just dragging that to the scene.
