How to update the Team Area value for Test Cases when using RQMExcelImporter?

 We are using CLM 6.0.1. We are successfully able to import Test Cases from Excel using RQMExcelImporter. The categories import is working fine too. We want to update the value of the predefined value of the drop down Team Area using the excel importer. We have created the required Team Areas in RQM and are able to select the value in the Test Case UI in RQM. We are trying to find the required respective change for the CFG file. Any help is much appreciated. I'm using "Scripts that create Test cases" sample as my base.
