How to use AutoWiring when looping through Subclasses?

I have a Sumfony 4.3 command that processes some data and loops through a number of "processors" to do the processing. The code uses a factory (autowired) which then instantiates the command.

use App\Entity\ImportedFile;
use App\Service\Processor\Processor;

class Factory implements FactoryInterface
{
    /** @var  array */
    private $processors;

    /** @var TestClausesInterface  */
    private $testClauses;

    private $em;
    private $dataSetProvider;
    private $ndviFromNasaService;
    private $archivalHashService;
    private $mailer;
    private $projectDir;

    public function __construct(
        TestClausesInterface $testClauses,
        ValidProcessorList $processors,
        EntityManagerInterface $em,
        DataSetProvider $dataSetProvider,
        NDVIFromNasaService $ndviFromNasaService,
        ArchivalHashService $archivalHashService,
        \Swift_Mailer $mailer,
        $projectDir)
    {
        $this->processors = $processors;
        $this->testClauses = $testClauses;
        $this->em = $em;
        $this->dataSetProvider = $dataSetProvider;
        $this->ndviFromNasaService = $ndviFromNasaService;
        $this->archivalHashService = $archivalHashService;
        $this->mailer = $mailer;
        $this->projectDir = $projectDir;
    }

    public function findProcessorForFile(ImportedFile $file)
    {
        ...

        if ($found){
            $candidates = $this->recursive_scan( $this->projectDir.'/src/Processor');
            foreach ($candidates as $candidate){
                if (substr($candidate,0,strlen('Helper')) === 'Helper'){
                    continue;
                }
                try {
                    $candidate = str_replace($this->projectDir.'/src/Processor/', '', $candidate);
                    $candidate = str_replace('/','\\', $candidate);
                    $testClassName = '\\App\\Processor\\'.substr( $candidate, 0, -4 );
                    /* @var Processor $test */
                    if (!strstr($candidate, 'Helper')) {
                        $test = new $testClassName($this->testClauses, $this->em, $this->dataSetProvider, $this->ndviFromNasaService, $this->archivalHashService, $this->mailer, $this->projectDir);
                    }

However I still have to:

• autowire all arguments both in the Factory and Processor top class
• pass all arguments in correct order to the Processor

I have around 70 subclasses of Processor. All of them use EntityInterface, but only a couple use SwiftMailer and the other dependencies.

As I am adding services to be used only by a few Processors, I am looking for a way to autowire these arguments only at the Processor level. Ideally, also without adding service definitions to services.yml

In summary, I would like to be able to add a dependency to any subclass of Processor, even if it is a parent class of other subclasses and have the dependency automatically injected.
