title: How do I customize the preview URL for draft posts in Wordpress?
body: <p>I've replaced the index.php file in my wordpress root dir with index.html (FYI - for reasons that are out of my control). </p>
  
  <p>Everything works great except the preview URLs for draft posts. This is completely understandable because the .html page rightly does nothing with the query params sent in. </p>
  
  <p>When I manually update the URL to point directly at index.php (which I left untouched in the webroot) the preview shows up just fine. </p>
  
  <p><strong>Is there anywhere in the WP admin where I can force admin links to the preview URLs to point directly at the index.php page?</strong></p>
  
  <p>TIA!</p>
  
  <p>FWIW - I'm an experienced web dev but know next to nothing about WP. </p>
