Shopify integration - required by date

The Shopify integration auto-populates the required by date as the order date.  For our business, and I would imagine many others, this is incorrect.  As a starting point, it would be great to NOT auto-populate this field with potentially incorrect information.  Ideally, the integration would allow for a standard turnaround time to be entered, for example, order date +2 business days.  But, simply allowing it to be blank would work for us too!
