  <p>But I want to show product image and product link in draft order.</p>
  
  <p>How can I do this?</p>
  
  <p>If line_item is custom one then it is showing Custom Title and no image and no option.</p>
  
  <p>I can't use variant_id because price is very different based on product options.</p>
  
  <p>So I need to use custom one but want to add product url and image in draft order.</p>
  
  <p>How can I do this?</p>
