Quantity Selection for Shopify Exchanges in Dear POS

We consolidate all of our Shopify Orders in Dear at the end of the day so that the sales tab isn't filled with 10's of individual orders. In Shopify we often have multiple sales of the same SKU on any given day. 

However, in Dear POS when we do an exchange of a Shopify Sale, we cannot select the quantity to exchange as 1. If we sold 2 of the same item on that particular day it forces you to exchange all of that particular SKU. Is it possible to add in a quantity selector for exchanges like you can for DEAR POS sales.
