Duration & Milestones visibility on same roadmap view Merged

Need to be able to show a continuous timeline (3-year broken into quarters) with both the initiative duration and specific milestones along the way. This is the issue we’ve encountered, our leadership wants to be able to see the iniative timeline, but then we have key milestones along the way that need to be represented in the same view (e.g. Goal target date, product ready date, etc…)
