Navigate to the Referees Module by clicking Referees and then Assigning and then go to the match chart.
Assign or copy assignments as normal.
How to Assign Using the Assignor Match Chart View
Select the match that you wish to rotate the crew on. On the right hand side, the assignment information will appear. Click the arrows next to each individual Referee's name to promote or demote the referee accordingly. A green flash will appear over the two positions that had a change. Click Save.
