Hello,
Unfortunately there is no such feature in the theme.
We’ll try to implement it future theme update.
Meanwhile you can add your content in Category Header and to make it shown at the bottom of the page you need edit the file wp-content/themes/legenda/woocommerce/archive-product.php and move the code <?php etheme_category_header();?>
(line 59) to line 126.
Please take our apologies for inconveniences.
Regards,
Eva Kemp.
