Adding Custom Column to College lists?
Please review this article.
Summary:
When a team member of a multi license plan creates a custom column, they do so from an individual student record because they don't have access to settings menu >> Default Data Columns. Only The Manager's account can set defaults across other accounts. When the custom column is created for the student record, the column is added to the student list automatically.
What if the team member wants to apply this column to all users:
Notify either your admin or super user and tell them that they need to go into settings > college data menu > find the custom column you created > select it to activate it > merge with all students.
What happens if I forget the second step?:
The next time one of your admin or super team members updates the defaults in settings, the column you created will be deactivated. If your columns are "randomly" disappearing this is likely the cause.
