For matrix tables you can add and view zonal references instead of the zone numbers. This will help the user with easier identification of zones in their model region.

To add a new zonal reference:

1. Right-click on any column > Zone labels
2. Click on New Zonal Reference
   
   
3. Rename the new zonal reference if desired by clicking on it and typing the new name.
4. Click on the column or row header to insert the zone names for each of the zones you wish to identify.
   
   
5. Save the matrix file to save the zonal reference.

To select a zonal reference to display:

Right click on any column > Zone Labels:

• Click on the check mark next to zonal references you wish to display, if any.
  
  
• Use the Filter.. section to look for a specific zone reference.
• Use Clear selection to uncheck the current zonal reference.
• Click on the X next to the reference zone to remove it.
