title: Dynamic parameter in href option in Aurelia Routing config.map
body: <p>This seems like a really simple issue, but it's driving me crazy...</p>
  
  <p>Does anyone know how I can specify a dynamic <strong>:id</strong> parameter in the href routing configuration option?</p>
  
  <p>The following unfortunately doesn't work:</p>
  
  <pre><code>    config.map([
          // ... default parameterless routing here
          {
              route:[':id/request'],
              moduleId:'processes/bdd/request/request',
              name:'Request', title:'Request', href:`#/bdd/request/${id}/request`, settings:{type:'Request', icon:''}, nav:true,
          },
          {
              route:[':id/requestAuth'],
              moduleId:'processes/bdd/request/requestauthorization',
              name:'RequestAuthorization', title:'Request Authorization', href:`#/bdd/request/${id}/requestAuth`, settings:{type:'Request', icon:''}, nav:true,
          },
          // ... some additional mappings here
      ]);
  </code></pre>
