title: Change WooCommerce processing order email notification recipient to a custom address
body: <p>When the order status in WooCommerce is set from <strong>pending</strong> to <strong>processing</strong> I can send an email to my customer. But I need to send an email only to a custom email adresse instead of the customer default address. </p>
  
  <p>Is there a hook or filter for the <code>functions.php</code> file?</p>
