Product Quantity variable needed for workflow in FLOW - Any thoughts on how to surface this?

Hello! We need to track products sold per customer ID within a time threshold. Based on the predefined values available in FLOW, it appears that “Get Order Data” returns the sort function of “Total Price” not “Total Quantity” for products (per customer). When ordering products, “Quantity” is a required field for each product, so it seems like this data is captured in the system yet it is not retrievable from “Get Order Data” in Flow. Does anyone know a workaround from “Total Price” to “Total Quantity” or where/if I can file a request ticket with Shopify for a future field enhancement??

In advance, thank you for your time and thoughts.
