Dynamic metadata

My codebase uses a pattern like this:

/** @var \App\Action\SimpleFooAction $simpleAction */
$simpleAction = $objectBuilder->getAction('simple_foo');
/** @var \App\Action\ComplexFooAction $complexAction */
$complexAction = $objectBuilder->getAction('complex_foo');

Docblocks were added here for illustration purposes, they don't belong to actual code. I think this is the exact problem that PhpStorm Metadata is designed to solve. However, the information I've found suggests that I need to hard-code every class name that exists, as in:

namespace PHPSTORM_META {
    override(
        \App\Builder\ObjectBuilder::getAction(0),
        map(
            [
                'simple_foo' => \App\Action\SimpleFooAction::class,
                'complex_foo' => \App\Action\ComplexFooAction::class,
            ]
        )
    );
}

Indeed, none of my attempts to populate map() with a function or variable rendered results.

I'm by no means familiar with the feature so I'd love to have this confirmed so I know I need to focus on another approach (such a script to generate this file dynamically).
