Ability to set Notification Policy approval on Event Contact Role

The ability to set a Notification Policy approval on an Event Contact Role (as opposed to a specific user as with current functionality), would allow for variable approval workflow based on specific Contact Roles within the event.

Event-specific Contact Roles that could benefit include budget managers, student organization advisors, or service providers, to name a few. This feature request expands the possibilities for communication and workflow in combination with new Event Save Emails and Event Form Rules features.
