[Feature Request] Create prefab from Render Group

In order to re-use more easily stuff that we build or to import stuff from templates, it would be great have the option to create Prefabs.

And my favorite option would be to create a prefab would be to right click on a Render Group and click on ‘Create a Prefab from Render Group’.
The Prefab would be added to the assets panel. We would be able to store materials, custom materials, camera presets etc.
The prefab would also have its own subgraph where we can store all the prefab transforms. And the prefab’ subgraph would be automatically added to the main graph when the prefab is created or added to the hierarchy.
