yii CListView relation sorting - yii

Question

Currently when i click on sort by in CListView generated table, it adds MODEL_NAME_2 to the url
?page=1&sort=MODEL_NAME_2.cat.desc
is there a way to remove it? or maybe rename it to something else? Or is this just how Yii works?
here is my actionIndex() in my controller
public function actionIndex()
{
$dataProvider=new CActiveDataProvider('MODEL_NAME_1', array(
'id'=> '',
'criteria' => array(
'with' => 'MODEL_NAME_2',
'together'=>true, //specifies whether the query should be run using a join
),
'sort'=>array(
'defaultOrder'=>'MODEL_NAME_2.cat ASC',
'attributes'=>array(
'MODEL_NAME_2.cat'=>array(
'asc'=>'MODEL_NAME_2.cat',
'desc'=>'MODEL_NAME_2.cat DESC',
),
'*',
)
),
'pagination'=>array(
'pageVar'=>'page'
)
));
$this->render('index',array(
'dataProvider'=>$dataProvider,
));
}
in my view
$this->widget('zii.widgets.CListView', array(
'dataProvider'=>$dataProvider,
'itemView'=>'_view', // refers to the partial view named '_view'
'enableHistory'=> true,
'sortableAttributes' => array('MODEL_NAME_2.cat'=>'Make'),
'pagerCssClass' => 'pagination',
'loadingCssClass' => '', //remove loading icon
'template'=>'
<div class="row">
<div class="col-md-12">
<div class="pull-left">{summary}</div>
<div class="pull-right">{sorter}</div>
</div>
</div>
<div class="row">
<div class="col-md-12">{items}</div>
</div>',
));
ideally i would like my url to look like this
mysite.com/bla/page/2/sort/cat/desc
basically using alot of / and no ? or &

In ListView definition change:
'sortableAttributes' => array('make'=>'Make'),
In your dataProvider
'sort'=>array(
'defaultOrder'=>'MODEL_NAME_2.cat ASC',
'attributes'=>array(
'make'=>array(
'asc'=>'MODEL_NAME_2.cat',
'desc'=>'MODEL_NAME_2.cat DESC',
),
'*',
)
),
