PHPSTORM how to automatically provide type hinting for all class methods?

Question

phpstorm

Good afternoon.
Is there a way in PHPSTORM to automatically provide type hinting for all class methods?
Those. there is some class

class Test
{
    /** @var string|null */
    protected $varString;
    
    /** return string|null */
    public function getVarString () {
        //...
    }
}

We need the opportunity, at will or otherwise, to specify the types returned by methods in the entire class.

class Test
{
    /** @var string|null */
    protected $varString;
    
    /** return string|null */
    public function getVarString (): ?string {
        //...
    }
}

I got the code that needs to be brought to the standards, but hundreds of files to be redone manually, this is still rubbish.
Thanks

Free hack: before declaring a method, enter /**and press Enter.

This is not called type hinting, but return type declaration.
