Additional Data saving

[ajnos]

I've added some extrafields to some forms.

What's the best way, to save the data with the datamanger?

Wouldn't it be good to have a event listener before, which sends $userInput $this->_input as reference, so we can add the own fields?
$writer->bulkSet($userInput);
Admincontroller_user

/**
  * Inserts a new user or updates an existing one.

  if ($userId)
  {
   $user = $this->_getUserOrError($userId);
   $this->getHelper('Admin')->checkSuperAdminEdit($user);
  }
  $userInput = $this->_input->filter(array(
