title: Localize records and update with DataHandler
body: <p>It is possible to localize records by using the &quot;localize&quot; command of the DataHandler</p>
  <pre><code>$cmd[self::TABLE_NAME] = [
    uid_of_the_original_record =&gt; [
      'localize' =&gt; language_uid,
    ]
  ];
  $this-&gt;dataHandler-&gt;start([], $cmd);
  $this-&gt;dataHandler-&gt;process_cmdmap();
  </code></pre>
  <p>This correctly adds a translated record to the DB, but with the copied strings of the original record. How is it possible to edit the properties of the localized record? By using the update command afterwards? If so, how do I get the uid of the added localization?</p>
