Hi There @jsnewton
To achieve that, first you need to setup a child theme and activate it by following our guide here (https://theme.co/apex/forum/t/setup-how-to-setup-child-themes/57). Then you can add the following code into your child theme’s functions.php file.
// Add Short Description
function woocommerce_after_shop_loop_item_title_short_description() {
global $product;
if ( ! $product->post->post_excerpt ) return;
?>
<div itemprop="description">
<?php echo apply_filters( 'woocommerce_short_description', $product->post->post_excerpt ) ?>
</div>
<?php
}
add_action('woocommerce_after_shop_loop_item_title', 'woocommerce_after_shop_loop_item_title_short_description', 5);
Then it should display as follows.

Please Note: We’re only providing a guidance on certain customizations as it would be outside our scope of the support. So if you require any further customizations, I would suggest you to contact a developer or service.
Thanks!
