title: How do I enable the "Upload files to Remote Host" feature in the Before launch section of a PyCharm Run/Debug Configuration?
body: <p>I'm running PyCharm Professional 5.0.4 and am referring to the feature described in the documentation <a href="https://www.jetbrains.com/pycharm/help/run-debug-configuration-python-remote-debug-server.html">here</a>.</p>
  
  <blockquote>
    <p><strong>Upload files to Remote Host.</strong> Select this option to have the application files automatically uploaded to the server according to the default server access configuration. For more information, see Configuring Synchronization with a Web Server and Uploading and Downloading Files.</p>
  </blockquote>
  
  <p>I have set a default Deployment (SFTP) and its mappings, and I can upload and download files via Tools->Deployment..  I have tried with the remote interpreter set to both the Deployment configuration and SSH Credentials.</p>
  
  <p>I've tried every setting that seems to make sense, but "Upload files to Remote Host" never appears as an option in the Before launch section of my Run/Debug Configuration.</p>
