Hi,
While there is no option you can change for this, it's possible to activate it locally with a small view override.
You want to edit the view file product / add_to_cart_ajax via the menu Display>Views. There, after the line:
$global_on_listing = $this->config->get('show_quantity_field') == 2;
you could add something like this:
$global $Itemid;
if($Itemid==XX)
$global_on_listing = true;
where XX would be the id of the menu item for the liked products listing.
That way, the global add to cart will be used on that menu item, and other products listings will display normally, with one add to cart button per product.
