CIN7 purchase order smart buyer

Hi with the cin7 smart buyer when creating a new purchase . It would be great if the products that are listed in the order cab be sorted in a logical order. Before emailing to the  supplier. At present we create the purchase  order with smart buyer. Then export the order to excel. We sort the products in excel. Then go back to cin7 and delete the products in the order. Then import the products in the sorted order back into the purchase order.
