We have several teams within our company. Each team is in charge of a Helpjuice "category". The team leader has the role of "collaborator" and the team members have roles of "draft writer". When a draft writer submits an article for Category A, it sends an email notification to Team Leader A, Team Leader B, and Team Leader C. I would like for all draft articles created in Category A to only notify Team Leader A. This could be accomplished by assigning specific Collaborators as moderators over each Category.
