Instead of using the shortcode, you can edit the PHP file responsible for the theme. <em>Kocuj Sitemap</em> plugin defines global PHP function which declaration is as follows: <code><?php function kocujsitemap_show_sitemap($homeLinkText = '', $class = '', array $exclude = array(), array $hideTypes = array()); ?></code>. The parameters <code>$homeLinkText</code> and <code>$class</code> perform the same function as the corresponding parameters in the shortcode <code>[KocujSitemap]</code>.
