Roadmap to add project summary task
When adding items to a row, Roadmap does not allow adding project summary row. This would be good feature because Roadmap can show start and end of project.
Thanks for calling this important scenario out here. We are planning to fix this, and we’ll keep you updated.
Please continue to keep sharing your feedback and scenarios.

This functionality already exist, but maybe not where you would expect it. If you go to the Schedule web part for a project, and make sure you have enabled the Project Summary task, you can select that and click on the button "Add to Roadmap" on the "Task toolbar". You can then select the roadmap where you want to show it.
