Currently, it is only possible to set the permission to the Roadmap at a higher level, which basically controls the access and grant all the options inside of it, so it is not possible to restrict some of its functions to specific users.

This causes problems as everyone who can access can change the data, like altering the health of an item. Ideally, would be possible to break down the permission inside the Roadmap (as we do with other areas), to allow only specific users to change data.
