Hi,
There is no option for that.
However, if you need to add additional content on the listing, I would recommend to create one or several custom fields of the table "category" via the menu Display>Custom fields.
Then, you can edit the file product / listing.php via the menu Display>Views.
There, you can move the block of code which displays the custom fields to have it near the end and thus after the products listing:
if(!empty($custom_fields_html)) {
?>
<div id="hikashop_category_custom_info_main" class="hikashop_category_custom_info_main">
<h4><?php echo JText::_('CATEGORY_ADDITIONAL_INFORMATION');?></h4>
<table class="hikashop_category_custom_info_main">
<?php echo $custom_fields_html; ?>
</table>
</div>
<?php
}
