Possible to add !important to styles set in controls?

Is it possible to have a control set !important on the styles it sets when creating elements? I thought I read somewhere that it is, but I can’t find that information anymore.

$this->controls['abc'] = [
    'css' => [
        [
	    'property' => 'color',
	    'selector' => '',
            '!important => true
        ],
    ],
];

I forgot to update this post when someone from the unofficial Bricks discord offered a solution. In my case I didn’t need the exclamation at the beginning.

$this->controls['foo'] = [
    'css' => [
        [
            'selector' => '.mine',
            'property' => 'color',
            'important' => true,
        ],
    ],
];
