Be able to add “related orders” to a “Production Order” already in place and vice versa add a “production order” to the “related orders” on the sales order

Now it is added automatically only one time when authorizing the sales order and allocating. But if for example we already have a “Production Order” in place for those same items, it would be very helpful to be able to select the “Production Order” in the related orders of that new sales order. That way a production order can have all the related orders (sales orders) that are fulfilled with that single Production Order.
