title: SourceTree Custom Actions. $SHA
body: <p>I spent last half an our searching for an explanation but I cant find it. </p>
  
  <p>In Source-tree in the Custom Actions there is a option to pass $FILE, $REPO, $SHA, as I understand from the explanation in the dialog, I can use more $SHA's but I always get only one. </p>
  
  <p>Is just a typo and I spent a good question on it or I just cant use it. </p>
  
  <p>Example of my action.</p>

  <p>I would like to inject more $SHA's in the command.</p>
  
  <p>Thank you.</p>
