To edit or delete a shift in the schedule, simply click on it. Then a modal will appear for you to change the shift to another type (e.g. an early to a late), edit the shift times as a one off or delete the shift completely.
To add a shift, hover over a surfer's day. If the day is empty or has less than 3 shifts already planned then a purple cross will appear - click that to bring up a modal to add shifts.
If a surfer's day has more than 3 shifts planned, click on the +more / +draft label to view all their shifts and make edits.
💡 In the schedule you can add as many shifts per surfer, per day as needed.
