Blog custom: post type

Hi, does anyone know if I can display posts in blog custom with a kind of post type?

<?php  
perch_blog_custom(array(
                'template' => 'post_in_list.html',
                'sort' => 'postDateTime',
                'sort-order' => 'DESC',
                'post-type' => 'post-es.html'
                                        ));
?>

Thanks!
