Release Gantt View - Add Epics in the Release view

We use Epics and Features for our roadmaps, but there is not a single view where we can see a Gantt with the three levels (Release, Epic and Feature) and the information can be collapsed hierarchically. In Releases>Gantt there is an option to visualize Releases>Features or Epics>Features and Releases at the top. There should be an option to at least configure a way to combine these two.
