Master features visually "Gantt" or spread across multiple releases when features fall in separate releases on Feature Board Merged

I have a large amount of master features that have many features and then requirements underneath them. I need to a quick way on the features board, where I may have to change releases for the features, to see how long the entire master feature is going to take, and what features below it are comprising the master feature.  At the very least, the master feature needs to spread across the multiple releases that its features are in. Even better would being able to expand it out showing the features themselves in their assigned releases while the master feature is shows above the groups as a parent.
