Often a course of study will have multiple units of study that are all identical except for the actual unit of study name. A menu item has been added against a Unit of Study, which opens up a wizard to duplicate the unit of study.
Tick all the units of study that you want to create. This creates a new record for each ticked unit of study. These are identical to the original unit of study except for the unit of study itself, and the completion status. Regardless of the status of the original unit of study, the newly created ones will all have "Not yet completed" as their completion status.
