Per-queue position sorts and filters for views

It would be great if we could expose specific views filters and sorts for each node queue. I'm encountering use-cases where I have nodes in multiple queues, but in a given view I really only care about filtering (or more likely sorting) from one specific queue. I think something along the lines of the code below can work:

  $qids = nodequeue_get_all_qids(NULL); // get 'em all
  foreach ($qids as $qid) {
    $tables['nodequeue_nodes_'. $qid] = array(
      "name" => "nodequeue_nodes",
      "join" => array(
        "left" => array(
          "table" => "node",
          "field" => "nid"
        ),
        "right" => array(
          "field" => "nid"
        ),
        'extra' => array(
          'qid' => $qid,
        ),
      ),
      "sorts" => array(
        "position" => array(
          'name' => t("NodeQueue: Queue Position in $qid"),
          'field' => 'position',
          'help' => t('When sorting by queue position, be sure the view is filtered to a single queue or the sort will not work very well.'),
        ),
      ),
    );
  }
  return $tables;
