title: Azure Data Factory specify custom output filename when copying to Blob Storage
body: <p>I'm currently using ADF to copy files from an SFTP server to Blob Storage on a scheduled basis.</p>
  
  <p>The filename structure is AAAAAA_BBBBBB_CCCCCC.txt.</p>
  
  <p>Is it possible to rename the file before copying to Blob Storage so that I end up with a folder-like structure like below?</p>
  
  <p>AAAAAA/BBBBBB/CCCCCC.txt</p>
