Create a "Planned" event status - the event is on the calendar without submission for approval.
All the campus departments gather weekly, for several weeks, to plan all their future events for the year, to minimize conflicts and create awareness to every one what is planned.
It would be nice to have a "Planned" status that will allow the event to be on the calendar without it being submitted for approval. The calendar filter tools and/or reports can be used to view the "Planned" events. Once ready for submission for approval, the event owner can change the status to new event and submit it.
