Yes it's possible to bulk edit products for your custom field '_text_field' (as in your linked question/answer).

You can add this custom field at the beginning or at the end of edit page.

• For the beginning you will use this hook: woocommerce_product_bulk_edit_start
• For the end this one: woocommerce_product_bulk_edit_end

The code (the custom field is at the beginning here):

// Add a custom field to product bulk edit special page
add_action( 'woocommerce_product_bulk_edit_start', 'custom_field_product_bulk_edit', 10, 0 );
function custom_field_product_bulk_edit() {
    ?>
        

            
                
                
                    
                     __( '— No change —', 'woocommerce' ),
                            '1' => __( 'Change to:', 'woocommerce' ),
                        );
                        foreach ( $options as $key => $value ) {
                            echo '' . $value . '';
                        }
                    ?>
                    
                
            
            
                
            
        
    is_type('simple') || $product->is_type('external') ){
        $product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;

        if ( isset( $_REQUEST['_t_dostawy'] ) )
            update_post_meta( $product_id, '_text_field', sanitize_text_field( $_REQUEST['_t_dostawy'] ) );
    }
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

This code is tested and works. You will get this:
