Begin by adding in the initial schedule for the student. Once that has been added, click onto the box corresponding to the student and day you'd like to add an additional schedule for. Please note, there will already be an initial schedule in that box, do not click directly on that schedule but just in the box surrounding it.

You will see the options in the screenshot below. Select if you'd like to add an additonal schedule for just that week or a recurring schedule.

Add the schedule, just as you did the initial one. Be sure to toggle to a different classroom if the student transitions classrooms throughout the day. Click "Save" once completed. The additional schedule will be added to the student's row.
