Each product in the process is placed as a separate order for the supplier, even if several products have the same supplier

I ask you to help the question, I checked different combinations of checkmarks when placing an order to the supplier, but the result is the same ... In the customer's order, there are several goods for one supplier, when switching to the "order to supplier" status, the action "create an order to the supplier" is performed and a separate order is created for each product to the same supplier (this problem appeared a long time ago, but now it is already very annoying) I tried to change the combinations of checkboxes (attached a photo), but in any case, a separate order is created, but I would like the goods to be grouped by suppliers in the order [file]11624[/file] [file]11625[/file]
