Thank you for getting back to us, @AChipOffTheOldBlock. I'll share some insights about auto-populating a site when creating a sales order.

QuickBooks Desktop cannot currently auto-populate a site when making a sales order. It also doesn't have the feature set of the ability to define a default site location. As I understand it, this would be advantageous to you and your company, so we will forward your recommendation to our Product Development Team to take the suggestion into account for a future update.

Let me know if you have additional questions about tracking inventory items. I'm always here to help. Have a great day.
