如何在yii2中添加条件取决于AppAsset类？

Question

There are some depends in AppAsset class in Yii2:

public $depends = [
    'yii\web\YiiAsset',
    'yii\bootstrap\BootstrapAsset'
];

Is there any way to add conditions for this depends like I do it with css and js?

public $jsOptions = ['condition' => 'lt IE 7']; 

Or, may be, you know another way to add conditions to bootstrap and yii JS and CSS files?
Thanks

UPD: I've added to config/web.php:

'components' => [
'assetManager' => [
    'bundles' => [
        'yii\web\YiiAsset' => [
            'jsOptions' => ['condition' => 'lt IE 7'],
        ],
        'yii\bootstrap\BootstrapAsset' => [
            'jsOptions' => ['condition' => 'lt IE 7'],
        ],
    ],
],

But, I've got this (as @arogachev recommends):

<script src="/assets/8fd244c6/jquery.js"></script>
<!--[if lt IE 7]>
<script src="/assets/bd48c465/yii.js"></script>
<![endif]-->
<script src="/assets/bd48c465/yii.gridView.js"></script>
<script src="/assets/db9cb9aa/js/bootstrap.js"></script>

UPD2 : answer

'yii\web\YiiAsset' => [
            'cssOptions'    => ['condition' => 'gt IE 7]>'],
            'jsOptions'     => ['condition' => 'gt IE 7]>'],
        ],
        'yii\bootstrap\BootstrapAsset' => [
            'cssOptions'    => ['condition' => 'gt IE 7]>'],
        ],
        'yii\bootstrap\BootstrapPluginAsset' => [
            'jsOptions'     => ['condition' => 'gt IE 7]>'],
        ],
        'yii\web\JqueryAsset' => [
            'jsOptions'     => ['condition' => 'gt IE 7]>'],
            'cssOptions'    => ['condition' => 'gt IE 7]>'],
        ],

You can customize vendor bundles through application config like that:

return [
    // ...
    'components' => [
        'assetManager' => [
            'bundles' => [
                'yii\web\YiiAsset' => [
                    'jsOptions' => ['condition' => 'lt IE 7'],
                ],
                'yii\bootstrap\BootstrapAsset' => [
                    'jsOptions' => ['condition' => 'lt IE 7'],
                ],
            ],
        ],
    ],
];

Or in runtime through assetManager :

use Yii;

...

Yii::$app->assetManager->bundles['yii\web\YiiAsset']->jsOptions = ['condition' => 'lt IE 7'];

Yii::$app->assetManager->bundles['yii\bootstrap\BootstrapAsset']->jsOptions = ['condition' => 'lt IE 7'];
