title: Is there built-in anyway to transform an AWS S3 pre-signed post in a pre-signed url?
body: <p>Given that I have an object post I got from <code>generate_presigned_post()</code> and I want to transform this into a pre-signed link, is there any way built-in <strong>boto3</strong>?</p>
  <p>I know there is a method to generate the link itself <code>generate_presigned_url()</code> but this out of scope right now...</p>
