Orchestration and UDC description in a Grid

Hi

I've a simple Orchestration the returns a variable number of item numbers along with the value of certain Cat Codes in the F4102. Ref example below

My question is , what's the best way to get the related UDC description for each of the "DW Category" codes values in the JSON response?

Running Orchestrator Studio 7.3.1.0 on Tools Release 9.2.3.4

-- Sample JSON Response---

{

 "G41 GTM V554102G Simple test" : {

  "tableId" : "V554102G",

  "rowset" : [ {

   "2nd Item Number" : "360-500-0100-01",

   "Description" : "EAB TIP080-SF-157-04-10 SEGSW",

   "DW Category 05" : "1115",

   "DW Category 06" : "340"

     }, 

 {

   "2nd Item Number" : "360-500-0120-01",

   "Description" : "EAB TIP055-SX-1710-0179 SEGSW",
