As a Confluence administrator, I'd like to be able to set up a Linchpin News Digest Configuration using the Sections I've already created, so that I don't have to list each category individually. Background: Currently the options to define which blog posts are included in a news digest are only configurable by space, label, or category. We have set up several parent sections, and would prefer to use those here instead of categories, since the categories are nested in the sections already.
