Local variable to object property refactoring?

I've had several cases this week where I started out with a local variable in a PHP class method (e.g., $myItem) and wanted to change it to be a class property (e.g., $this->myItem). Does PhpStorm support this sort of refactoring? I can do it by hand, to be sure, but I'm getting spoiled by PhpStorm's power. Thanks!
