Link to task/milestone or phase from roadmap to project
Should be possible to go straight from the item in roadmap to project plan for editing.
This is possible. To do this click the item in the roadmap to bring up the details pane. In the pane under Connections you should see the name of the task the roadmap item is linked to. If you click that, we'll take you to the project and task (if using Project for the web) the item is linked to.
