Automatically link production order to sales order when creating production order MRP Display screen from Manufacturing button

Automatically link production order to sales order when creating production order  MRP Display screen from Manufacturing button
 

I try to override below delegate but not getting production order number. I want to display new created production order under references tab sales order details as shown below.
 

  public delegate void GenerateProductionOrdersDelegate(List<AMOrderCrossRef> list);
        [PXOverride]
        public void GenerateProductionOrders(List<AMOrderCrossRef> list, GenerateProductionOrdersDelegate baseMethod)
        {
            baseMethod(list);
}

If anyone has the knowledge or some guidance on how to do it  I would appreciate it very much.
Thanks
