Country Restrictions for WooCommerce

Hi, I would need, if possible, to have development side filters on the returned payloads on all kinds of restrictions.

If it is possible to do it at least on the hide action of add to cart buttons, to both global rules and at the product level.

For example:
on line 752 of class-cor-front.php
instead of:
echo ”;
manage it with:
echo apply_filters(‘placeholder_test_filter_hook’, ”);

So that I can add more custom code that I need.

Thanks.
