A status to prevent elements sending for candidates with a status of booked.
The reason for his is because Waterside only know who is going to attend (50% of their courses) based on a sign in sheet they get back from the course, so turning off placeholders is not an option as they need to use these.
However.... when Phillipa back fills a course date that was placeholders she triggers out joining instructions for a course that has already been attended and completed because the joining instructions are linked to a candidate status of 'booked'
