Applicant select the sessions the are interested in when they apply. They are allowed to select sessions across different partners if they are all in the same city.
When an applicant selects a single session from a single partner, that session is automatically assigned as the Assigned Term. There is no automatically Assigned Term when the applicant selects more than one session.
When an applicant selects sessions from more than one Partner, the system will try to assign a Partner to the application using these rules
The Edit Application Modal will display all the sessions that have not yet ended. This is so that you can assign an already started session in case they begin late.
