Hello, @Marcel,
Unfortunately, there is no such option in our theme for this, and it is the default WooCommerce functionality, our theme does not have any influence on it, so this requires extra Customziation.
You can read this article as it might helpful for you: https://www.cloudways.com/blog/woocommerce-product-sort-and-display/
If you want paid Customization services submit a customization request to WPKraken team.
Regards 8Themes Team.
