I manage a Program of hybrid agile projects and want to simplify my reporting to our management. I have previously produced the program on a page view in MS Powerpoint, with each project broken down into a set of bars that indicate a project stage - Define, Initiate, Requirement Analysis, Design & Development, Testing, Release. I don't have the skills to simply replicate this view in Advanced Roadmap, meaning that I don't see how I can group tasks by project stage within a project.
I've explored Advanced Roadmap and can represent epics/tasks on the Advanced Roadmap, but this is not the right level of detail for management.
