Is it possible to match the # part of a route in React Router 4 : <p>In my app, I'd like to match both the path and the hash to different components.  For example:</p>

<pre><code>/pageA#modalB
</code></pre>

<p>Would show PageA as the main page, with modalB over the top.
I've tried the following, with many variations of the path property:</p>

<pre><code>&lt;Route path="#modalB" component={modalB}/&gt;
</code></pre>

<p>But nothing works.</p>

<p>In React Router 2 inside a modal 'controller' component, I would use:</p>

<pre><code>browserHistory.listen( (location) =&gt; { //do something with loction.hash })
</code></pre>

<p>I was hoping for something a little more elegant in V4</p>
