WooCommerce Shipping Multiple Addresses

Shipping Multiple Addresses adds a multiple shipping option at checkout. A shopper splits one cart across several destinations and assigns products and quantities to the addresses they choose, instead of placing a separate order for each recipient.

The Cart Duplication feature copies the contents of a cart and sends the same set of products to several addresses. Customers can mark items sent to an address as a gift, which signals that an invoice should not be included in that shipment. More than one address can be saved to a customer account. It supports all WooCommerce shipping methods.

You turn it on by enabling multiple shipping in the shipping methods settings.
