<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>I have a use case that requires sending separate emails to different GovDelivery topics at the same time. However, I've discovered that when I call <code>\Drupal::service('govdelivery_bulletins.add_bulletin_to_queue')->addTopic()</code> for the second email, that the service still remembers the topic from the first email and therefore queues up an email with two topics.</p>
<p>There doesn't appear to be any way to erase the previous topic or otherwise reset the service back to its initial state prior to sending the second email.</p>

<p>Add a <code>reset()</code> function that re-initializes all of the private variables that only have public <code>addVariable()</code> functions that append values to the existing variable's value.</p>
