More actions for Previously imported items

Hi,

I needed something similar for this, importing sports matches so wanted to set a match "status" field to "result" when the item was no longer available in the live feed.

You have to create a new non-configurable (no options) action for it to show up, take a look at core/lib/Drupal/Core/Action/Plugin/Action/SaveAction.php as an example. In the execute method you'd need to set your boolean field value something like:

  /**
   * {@inheritdoc}
   */
  public function execute($entity = NULL) {
    $entity
      ->set('field_match_status', 'result')
      ->setChangedTime($this->time->getRequestTime())
      ->save();
  }

Hope that helps
Tom
