Be able to add and show master features on the release overview window (release roadmap) Merged

As a project manager when I am building out my release I want to be able to see the whole release in the roadmap view as shown on the release overview. However, I am not able to view or group features by the master features that they belong to. You should be able to add a master feature to this view and expand it to see the feature that are in that master feature.
