title: Intellij: Refactor Change Method Signature to change an abstract method from void to Int, but also add return -1 to all subclasses
body: <p>Long story short personal project of mine, I am trying to re-do the implementation of something. However, there are many uses of this method and it would take me too much time to do it manually.</p>
  <p>Using the change method signature window, I can easily change an abstract method of</p>
  <pre><code>public abstract void run(int a, int b);
  </code></pre>
  <p>to</p>
  <pre><code>public abstract int run(int a, int b);
  </code></pre>
  <p>That part is easy enough and I know how to do it.</p>
  <p>However, I'd also like to be add:</p>
  <p>Before:</p>
  <pre><code>@Override    
  public void run(int a, int b) {
     /* irrelevant code here */
  }
  </code></pre>
  <p>After:</p>
  <pre><code>@Override    
  public int run(int a, int b) {
      /* irrelevant code here */
    return -1;
  }
  </code></pre>
  <p>Is this possible with any of the tools Intellij has to offer?</p>
