Of course, please open related.php which is found in Neighborhood/WooCommerce/single-product and find line 31:
//$woocommerce_loop['columns'] = $columns;
$woocommerce_loop['columns'] = 4;
Change the 4 to 6, save, and then add this to your custom css:
body.woocommerce .has-no-sidebar ul.products li.product, body.woocommerce .has-no-sidebar .upsells.products ul.products li.product {
width: 170px;
}
