Add an attachment to a Change after the Implementation Stage

Add an attachment to a Change after the Implementation Stage

Is it possible to add an attachment to a Change Request after it has completed the Implementation Phase?  When we execute a change, there is usually a PDF we generate of the deployment to production.  We would like to attach this PDF to the Change Request, but I do not see an Attach File link in the Review or Closing phases.
