title: FeathersJS: Call service with express route parameters
body: <p>I have a service defined like this: </p>
  
  <pre><code>app.use(`/teams/:${id}/members`, teamsMembersService);
  </code></pre>
  
  <p>Now I would like to call this service from another service. According to the documentation I can access different services using the app object. 
  Like so: </p>
  
  <pre><code>let result = await app.service('teams').find();
  </code></pre>
  
  <p>That works well. Unfortunately this does not: </p>
  
  <pre><code>let result = await app.service('teams/1/members').find();
  </code></pre>
  
  <p>Because the service is undefined. </p>
  
  <p>How can I call this service with route parameters? </p>
