Including inherited code in an override

Override seems to completely replace a function’s code.

Is there any way to “append” to the superclassed function instead of replacing it?

i.e. - so that both traces show in this example:


package {
     public class Top {
          public function doSomething() {
               trace('top');
          }
     }
}

package {
     public class Bottom extends Top {
          public override function doSomething() {
               trace('bottom');
          }
     }
}
