title: Override typescript enum descriptions
body: <p>I have the following enum generated somewhere outside of my app:</p>
  
  <pre><code>enum Colors {
      Red = "RED",
      Green = "GREEN",
      Blue = "BLUE",
  }
  </code></pre>
  
  <p>This enum is used as a type for generated interface property</p>
  
  <pre><code>interface MyObject {
    objectName: string,
    objectColor: Colors
  }
  </code></pre>
  
  <p>Is it possible to override enum string values so that same enum value could have new descriptions like this:</p>
  
  <pre><code>enum Colors {
      Red = "RED car",
      Green = "GREEN grass",
      Blue = "BLUE sky",
  }
  </code></pre>
