In the Classic TWS layout you can add the columns for "Order Ref." (see How do I add a column to my TWS page?). When you create an order click in the "Order Ref." field on the TWS order row and add the desired reference number.
Please Note
- You can add the Order Reference column to any TWS page/tab as well as your TWS Pending (All) tab.
