Filter releases by workspace in strategic roadmap

Using the strategic roadmap, we would like to be able to expand each initiative to view its child features, while viewing only the releases assigned to this specific workspace. As it stands, this roadmap view shows us every linked release across every workspace in our org, which is too cluttered for what we need. If we could filter releases by workspace, it would give us relevant insight against our roadmap and we would no longer need to minimize the releases to get them out of our way.
