Hello PR,
Unfortunately, the default WooCommerce option does not provide the ability to add more sorting options to the shop page. It is possible to do so through additional customization, such as the one found at https://rudrastyh.com/woocommerce/sorting-options.html If you require something more advanced, you may need to look for an additional plugin at your own risk or contact WooCommerce support for assistance.
Best Regards,
