Format Space around object operator

Hy all,

I'm testing phpstorm and there's one option that i can't find, to format some space around object operators ( in PHP ).

Let's say that you've got this piece of code:

public function __construct() {
        // create array with URL parts in $url
        $this->splitUrl();

        // Do some other stuff...
}

Then i wan't an space around the object operator ( -> ) like so:

public function __construct() {
        // create array with URL parts in $url
        $this -> splitUrl();

        // Do some other stuff...
}

where can i customize my own scheme just like Netbeans with all the checkboxes...
