是否可以在柔性滑块上再添加一个选择器

我想知道，是否可以将另一个选择器添加到Wooteme的flexslider？在不同的页面上，我使用不同的幻灯片样式，这就是为什么我想在$.flexslider.defaults中添加一些类似的内容：

selector1:".my_slides > li",

到flexslider中的选择器，而不删除默认

selector:".slides > li".  

我试着做一些类似的事情

selector:".slides > li", ".my_slides > li", 

但它不起作用。

这是我使用.slides和.my_slides的代码（我不知道是否有区别，但我在Wordpress中使用它）：

    $format = get_post_format();
    if(empty($format)) {
        $format = 'standard';
    }
    if( $format == 'standard' || $format == 'gallery' || $format == 'image' || $format == 'video' ) {
        get_template_part( 'includes/' . $format );
    }
}
