Hello,
The add to cart is WooCommerce functionality and our theme doesn’t influence it. It is controlled by WooCommerce.
Anyways, Thanks for sharing the suggestion/feature request with us, I am forwarding this to our development department for considering adding it in the theme, but I am not giving you the guarantee for that because please note that a theme cannot satisfy all requirements as it may occur theme heaviness. Sometimes it may require your own customization. So if the development department finds it fit with the theme environment then surely they will look through it.
Best Regards.
