Trying to get total page views on Global Hierarchy on a particular section (including all stories, blogs, pages linked to that section and not just the sub section)

If you already have a dimension that combines each section, you can use workspace and drag the dimension, then page views as a metric.

If you don't have a dimension that combines the sections, you can create a classification to combine them. Once you've combined values via a classification, you can drag the classification dimension in workspace, then page views as a metric.
