title: Is there a simple way to tell alembic to migrate to a specific revision?
body: <p>Alembic has commands to upgrade and downgrade to a specific revision, e.g. on the command line:</p>
  
  <pre><code>alembic upgrade &lt;target-revision&gt;
  </code></pre>
  
  <p>And</p>
  
  <pre><code>alembic downgrade &lt;target-revision&gt;
  </code></pre>
  
  <p>Is there a simple way to migrate to a specific revision if you don't know whether it's an upgrade or a downgrade? i.e.</p>
  
  <pre><code>alembic migrate &lt;target-revision&gt;
  </code></pre>
  
  <p>I can work out the direction by looking at the history, current and target revisions, but this feels like fighting the library. Am I missing something or is there a reason why this isn't provided out of the box?</p>
