You can sanction players for your association.
Go to Player Sanctions (Menu > Manage > Players/Teams > Player Sanctions)
1. Select the Association you want to sanction for.
2. To help filter, you can choose the Division you want to sanction.
3. Check the Is Sanctioned check box.
The date will be stamped automatically to the date you check the box.
Once you are done sanctioning (You can always come back and sanction more later) you can export the file to Excel.
