Is it possible to merge (merge) the scope of the current class with the scope of the parent class in yii?

Question

Yii

Hello,
For example:

class ActiveRecord extends CActiveRecord
{
...
return
        [
            'published'=>
            [
                'condition'=>'exist = ' . self::STATUS_PUBLIC,
            ],
       ];
...
}

And there is a successor class:

class Bids extends ActiveRecord
{
...
// тут  необходимо слить текущую группу scopes с родительской, но не перебить при этом
...
}

In general, it would be cool to get such a model after these manipulations:

$model = Bids::model()->published()->busy()->findAll();
