Currently it's not supported, since the tab does not contain this buttons

var button = Sunstone.getButton(tab_id,value);

    "getButton" : function(tab_id,button_name){
        var button = null;
        var buttons = SunstoneCfg["tabs"][tab_id]["buttons"];
        button = buttons[button_name];
        //not found, is it in the list then?
        if (!button && buttons["action_list"])
        {
            button = buttons["action_list"]["actions"][button_name];
        }
        return button;
    }
