Assign managers to regions and sites by associating PTT Pro user IDs with the region or site. Every region, child region, and site may have one or more managers and a single PTT Pro user may manage multiple regions. To assign managers to regions and sites, use one of the following methods:
          
- Use the Regions/Sites tab in the ZEMS portal to associate managers with sites.  
- Use the Users tab in the ZEMS portal to associate managers with regions or sites. 
- Use the ZEMS API Region.Managers controller to associate managers with regions or sites.
