Just like regular roadmaps, you can export the items in a Master roadmap to a CSV file. You can also export a Master roadmap's view as a PNG or HTML file, as well as publish it to a URL.
NOTE: Since Master roadmaps have only one view created by rolling up source views, you don't need to select the view you want to export or publish as you do when exporting a regular roadmap.
