Yes there is,
In your admin file add this lines:
if (!isset($xoopsTpl) || !is_object($xoopsTpl)) {
include_once(XOOPS_ROOT_PATH."/class/template.php");
$xoopsTpl = new XoopsTpl();
}
After that you can assign template vars as usual.
At the end of the file use this:
$xoopsTpl->display( 'db:your_template_name_here.html' );
You must declare that template in the module's xoops_version.php as you do for any other template and use this code after xoops_cp_header(); and before xoops_cp_footer();
