title: FacetWP - how to put custom order by
body: <p>I create custom fields using Pods Admin and FacetWP do show and filter on page.</p>
  
  <p>but I need to change "order by" to custom field called "volta-rapida-tempo". </p>
  
  <p>Like this: </p>
  
  <pre><code>&lt;?php
      return array(
        "post_type" =&gt; "volta_rapida",
        "post_status" =&gt; "publish",
        "orderby" =&gt; "volta-rapida-tempo",
        "order" =&gt; "ASC",
        "posts_per_page" =&gt; 10
      );
  </code></pre>
  
  <p>How can I do this correctly?</p>
  
  <p>Thanks</p>
