Sage ERP Mas 90 - Customize Custom Look up with Bin location

SOLVED

Using version 4.50.70.0. I need to add bin location to the item inquiry and item maintenance look up fields. So when I go to Item Inquiry or Maintenance, then the look up magnifying glass and I use the custom tab. I can add just about everything I want EXCEPT bin location.

How do I add bin location? I know it's an available field in the explorer, but I want it in the lookup.

 

Please!
