This is available. The Shopify connector exposes refund quantities in the orders table: Order Refunded Items Quantity (id: order_refunds_quantity) for the order total, and Line Item Refunds Quantity (id: line_item__refunds_quantity) for the quantity refunded per line item. Add either field to your query to get refunded quantities.
