Create document structure from Sitemap/Mindmap

I would love to have a functionality where you can create a sitemap or import from a sitemap/mind map and then Modx automatically creates the document tree based on that document. Some mind map software can export to txt or csv, for example a txt file might look like this:



Modx would then create a document structure like this:



Of course, an Ajax app where you can fill in your sitemap would be cool too
