title: How to pre-fill select shipping method dropdown on step2 of shopify checkout page?
body: <p>I guess the title pretty much explains what I want to do.</p>
  
  <p>The thing is we have to provide some options based on the shipping method, so we developed a custom app for that,and provided the options on the checkout page.(Screenshot below)</p>

  <p>Now when the user clicks on checkout and goes to the Shopify checkout page, he has to select the shipping method again on step 2 of the checkout page.</p>

  <p>So is there a way to prefill the selected shipping method based on the selection made by user??</p>
