It would be nice if there was a way to let officials self assign a specific level but require an approval by the assignor before its final.
An approval workflow on sport levels would solve this I believe.
Workflow would be as such:
1. Official self assigns a game to himself
2. This particular level has the workflow configured on it in the admin settings
3. An email is kicked off to the assigner
4. The assigner signs in and has to click Approve or Accept
