title: Jenkins Multi-Configuration Build - How do I specify the value of a multi-configuration axis in Email-Ext (Editable Email Notification)?
body: <p>I've searched and have not found what content token that I would use to note the value of an axis that is used on a multi-configuration build for the email?</p>
  
  <p>This shows up in the normal email but is a blocker for us getting to the better email notifications?</p>
  
  <p>I will accept that this is in an ENV variable somewhere, but have been unable to locate it yet.</p>
  
  <h1>For reference</h1>
  
  <p>We'd typically add an axis of a label, slaves or user-defined (image below):<br>

  <p>Then we would add values:<br>
  <img src="https://i.stack.imgur.com/jdEWK.png" alt="User defined axis"></p>
  
  <p>Those values show up in the normal email notification (note the <code>&gt;&gt;</code> to signify all axes of the multi-configuration build that passed or failed:

  <p>I can not seem to get to them in email. I've tried looking for environment specific values and I've tried <code>${ruby}</code> as a content token, but have been unable to find any information on this thus far.</p>
