Remove workspace default reports from Roadmaps Overview

On the Roadmaps overview page, there are a bunch of default reports that clutter up the All view. There is a Release Plan and Roadmap listed for every workspace. When you click into them, it just drops you on the default gantt for the workspace or the features roadmap.

I do not find these reports to be very helpful, and they make it harder to find what I need from the Roadmaps overview.
