Symfony Messenger - Subscribing multiple Handlers to Messages

AgencyPublisher.php

<?php

namespace Acme\TemporaryWork\Infrastructure\ProcessManager;

use OldSound\RabbitMqBundle\RabbitMq\ProducerInterface;
use Prooph\EventSourcing\AggregateChanged;
use Acme\TemporaryWork\Domain\Model\Agency\Event\AgencyHired;
use Acme\TemporaryWork\Domain\Model\Agency\Event\AgencyModified;
use Acme\PersonnelManagement\Infrastructure\RabbitMq\Producer;
use Symfony\Component\Messenger\Handler\MessageSubscriberInterface;

final class AgencyPublisher extends Producer
    implements MessageSubscriberInterface
{
    public function __construct(ProducerInterface $producer)
    {
        $this->producer = $producer;
    }

    public function __invoke(AggregateChanged $event): void
    {
        $data = array_merge(
            ['agencyId' => $event->agencyId()->toString()],
            $event->payload()
        );

        switch (get_class($event)) {
            case AgencyHired::class:
                $this->publish($data, 'acme.personnel.agency.hired');
                break;

            case AgencyModified::class:
                $this->publish($data, 'acme.personnel.agency.modified');
                break;
        }
    }

    public static function getHandledMessages(): iterable
    {
        yield AgencyHired::class;
        yield AgencyModified::class;
    }
}

Is there a way to subscribe a symfony messenger message to multiple handlers without adding code to the class via MessageSubscriberInterface - maybe via config?
