If you want that functionality right now you can use https://github.com/liquidweb/woocommerce-custom-orders-table I've used it multiple times, and have never had problems. There actually is a good chance custom tables could land in WooCommerce this year as all they have to do is integrate that plugin into WooCommerce. The plugin has already gotten heavy use on many big websites, and I know that the WooCommerce team knows about the plugin's existence.
