Hi Jeff,
You can filter a Project Burndown report by Epic. Also the Epic
Dashboard allows you to drill into an Epic and see what has been and
has not been completed. There isn't currently a feature that
automatically allows a way to look at a backlog and determine what is
"below the line", if that is what you're looking for. That would be a
great idea to add to Ideaspace, or vote up if it is already there
(
