Control "add field" and "add method" placement

Is there a way to control where fields/methods get added to a PHP class?
ie: clicking "add field" on an undefined object variable currently adds the variable to the very end of the class. Is it possible to place near the top?


Also if I type this method call:

$this->some_new_method($a,$b,$c,"something");

hover over some_new_method and click the "add method" helper, is there a way for it to create something like this:

/**
  * @param  $a
  * @param  $b
  * @param  $c
  * @param  $arg4
  * @return   
  */

public function some_new_method($a,$b,$c,$arg4){
}

instead of just:

function some_new_method(){
}


Thanks heaps,
Dave
