title: How do you add more property values to a custom object
body: <p>If I do this</p>
  
  <pre><code>$account = New-Object -TypeName psobject -Property @{User="Jimbo"; Password="1234"}
  </code></pre>
  
  <p>How do I add <strong>additional</strong> User and Password values to <code>$account</code> without overwriting the existing one?</p>
  
  <p>I cannot pre-populate <code>$account</code> from a hashtable. I don't know all the users and passwords at runtime.</p>
