Hi Mike,

Thanks for your patience.

Here are replies from our developer: Unfortunately, WoodMart theme does not support custom stock status, but we can provide code that will remove the out of stock label. Also, if you need to add some custom labels, you can also do so using this code.

add_filter('woodmart_product_label_output', function ( $labels ) {
	foreach ( $labels as $key => $label ) {
		if ( strpos( $label, 'out-of-stock product-label') !== false ) {
			unset( $labels[$key] );
		}
	}

	// Your custom code here.

	return $labels;
});

Regards,
