If you want to assign a unique ID to your Athletes and/or Teams. You can initiate the assignment within the respective list:
For Individual Athletes:
Go to Athletes
Scroll towards the bottom and click "Quick Athlete IDs"
Select a division
Enter the starting ID you'd like to assign that division.
For Teams:
Go to Teams
Scroll towards the bottom and click "Quick Teams IDs"
Select a division
Enter the starting ID you'd like to assign that division.
When assigning team ID's, team mates will also be assigned a unique ID as well. For sample, if a Team of 4 is assigned a team ID of '200', Team Member 1 would have an ID of 200-1, Team Member 2 would have 200-2, and so on.
