Admin new order allows out of stock products

Hello,
How can I prevent adding admin new orders with out of stock products? It seems woocommerce doesn’t care if a product is in stock or not when I’m adding orders manually. The only way to check if a product is in stock or not is to click on the product’s row and then ‘increase’ or ‘decrease’ stock. Very inconvenient when taking orders by phone.
Any help will be greatly appreciated, thank you.
