Allow roadmaps of Master Features to expand to show linked Features

We have a number of Master Features we would like to show on a custom roadmap quarterly view. We can do that today, no issue.

We have a number of Features tied to those Master Features. To see that information in the same custom roadmap quarterly view, we must create a second report. We do this today.

We would like to have one report where we can nest/expand the Master Feature and see the Features below it in the same quarterly view. Another way to describe: I'm viewing a roadmap of Master Features, I click the Master Feature, it maps all the individual features inside of it on the same roadmap.
