title: Setting the output file name in a biztalk send port
body: <p>Good afternoon,</p>
  
  <p>I'm trying to set the output file name in a send port and the available file name macros won't quite work.</p>
  
  <p>I need something of the form "file.YYYYMMDD_HHMMSS". There's a datetime combined macro (with the wrong format), a time only macro, but no date only macro.</p>
  
  <p>I don't have an orchestration for this process.</p>
  
  <p>Is there any way I can set the file name from within a map or a pipeline?</p>
  
  <p>Thanks!</p>
