Scenes Audit

Does anyone know a way of making a list of all the viewport scenes in Layout?

My SU files (one for each floor) have become very bloated with scenes becasue my boss wanted a different arangement of sections, so now I have a bit of a mess of scenes in all my files.

Maybe a script that parses the LO file and spits out a list of scenes and their reference?

That way I could go in and delete all the unused scenes and regain my sanity!
