title: How to add a file in shelved change list in Perforce?
body: <p>I edited a file and then shelved the changes in it with shelved changelist <code>X</code>. Now I edit another file. How can I add this file in already existing shelved changelist <code>X</code> or generate a new changelist containing changes in both files?</p>
  
  <p>Thanks.</p>
