The portfolio hierarchy is as follows:
The enterprise has one or more "Line Of Business" items
Each "Line of Business" has one or more "Investment Initiative" items
Each "Investment Initiative" has one or more "Epic" items
Each "Epic" has one or more "Program" items
Each "Program" has one or more "Feature Group" items
Each "Feature Group" has one or more "Feature" items
Each "Feature" has one or more user stories
I'm trying to solve the problem of two organizations, each with their own "Feature Group" items wanting to "own" my "Feature" and its associated user stories.
