Is there a way to specific position of my action in idea OpenAPI dynamic? Follow

i know that i can use :

<![CDATA[
DefaultActionGroup fileMenu = (DefaultActionGroup) ActionManager.getInstance().getAction(groupid);
]]>

But i dont know how to add my action to the File menu group in index 4. There is a method add(AnAtion,Constraints) in DefaultActionGroup , but i didnt see any way to specific AnAtion position.

Thx
