Yes. When creating an order, if you want to add a product not already in your inventory, simply type the product name (it's a good idea to include case size too) into the Product Name field and click the green +Add as new product button that appears below the product name. Then add quantity and unit price as you would normally. The product will be saved in your inventory as a temporary product. If you'd like it to become part of your standard inventory and visible to all buyers, please update its information in your inventory and activate it.
