PhpStorm live template variable wrap/surround

Question

I have a Sublime Text snippet I would like to convert to a PhpStorm's Live Template. Currently I am stuck with the possibility to wrap already defined variables.

e.g.

${2:${1:HOOK}}_mail

A first tab in sublime text would output the following.

MY_HOOK_mail

A second tab would then allow me to overwrite the MY_HOOK

MY_OVERWRITE_mail

Would this be possible with live templates?

As reference the sublime text snippet I am trying to convert: https://github.com/iampuma/d7ssnippets/blob/master/hook_mail.sublime-snippet

• Reference how this actually works in Sublime Text (line 8):

Live template:

/**
 * Implements hook_mail().
 */
function $MODULE_NAME$_mail($key, &$message, $params) {
  switch($key) {
    case '$MODULE_NAME1$_mail':
      $message['subject'] = $SUBJECT$;
      $message['body'][] = '$BODY$';
  }
}

The trick is just to use the previous variable as default value. E.g:

Live template:

/**
 * Implements hook_mail().
 */
function $MODULE_NAME$_mail($key, &$message, $params) {
  switch($key) {
    case '$MODULE_NAME1$_mail':
      $message['subject'] = $SUBJECT$;
      $message['body'][] = '$BODY$';
  }
}
