Shopify Order_Line_Items missing timestamp

The Shopify Order_Line_Items table is missing a timestamp field needed to schedule a dataflow connection to pull in order details that relate order and products from Shopify into AEP. I was able to schedule data connections for the Orders and Customers tables. However, the Order_Line_Items table is needed to tie the products to the orders. Without this timestamp field we cannot use this Shopify connector.
