MVC Authorization - multiple login pages

Question

I have a the following methods in an MVC Controller which redirect to the login page when a user is not logged in.

[Authorize]
public ActionResult Search() {
  return View();
}

[Authorize]
public ActionResult Edit() {
  return View();
}

Is there a quick/easy/standard way to redirect the second action to a different login page other than the page defined in the web.config file?

Or do I have to do something like

public ActionResult Edit() {
  if (IsUserLoggedIn)
    return View();
  else 
     return ReturnRedirect("/Login2");
}
