Autocomple for Objects from Factory

Hi,

I think this should be a problem for many people (and so I hope, there is a solution.

We have a Factory in our Application. It is used like that:

$order_coo = MainFactory::create_object('Order');

So the $order_coo is an Instance of the Order-Class.

I know, that I can tell PHPStorm (or IntellJ Image may be NSFW.
Clik here to view.) that with using PHPDoc like this:

/** @var Order $order */
$order = MainFactory::create_object('Order');

But is it possible to tell the Factory, that it will alway return an Object from the Class which is the parameter?

So I don't have to make every call from Manfactory wrap with that PHPDoc /** @var Order....
