How to add a secondary output in a Symfony2 Console application?

I have a Symfony2 Console application with a few commands:

$application = new Application();

$application->add(new MyCommand1());
$application->add(new MyCommand2());

$application->run();

When running the application, I'd like the output to be redirected both to the console and to a file.

I can use StreamOutput for this, but it looks like I can only provide such an output object if I manually run one of the commands:

$input = ...;
$output = new StreamOutput(fopen('output.log', 'a'));

$command = new MyCommand1();
$command->run($input, $output);

But this is not what I want.

Is it possible to add a secondary output to the Application itself? So that all commands output both to the console, and to a file.

To achieve this task, I would create my own Output.

class MultipleOutput implements OutputInterface
{
    protected $outputs = array();

    public function __construct(array $outputs = array())
    {
        $this->setOutputs($outputs);
    }

    public function setOutputs(array $outputs = array())
    {
        foreach ($outputs as $output) {
            $this->addOutput($outputs);
        }
    }

    public function addOutput(OutputInterface $output)
    {
        $this->outputs[] = $output;
    }

    public function write($messages, $newline = false, $type = self::OUTPUT_NORMAL)
    {
        foreach ($this->outputs as $output) {
            $output->write($messages, $newline, $type);
        }
    }

    public function writeln($messages, $type = self::OUTPUT_NORMAL)
    {
        foreach ($this->outputs as $output) {
            $output->writeln($messages, $type);
        }
    }

    public function setVerbosity($level)
    {
        foreach ($this->outputs as $output) {
            $output->setVerbosity($level);
        }
    }

    /**
     * Returns only the first one
     */
    public function getVerbosity()
    {
        foreach ($this->outputs as $output) {
            return $output->getVerbosity();
        }
    }

    public function setDecorated($decorated)
    {
        foreach ($this->outputs as $output) {
            $output->setDecorated($decorated);
        }
    }

    /**
     * Returns only the first one
     */
    public function isDecorated()
    {
        foreach ($this->outputs as $output) {
            return $output->isDecorated();
        }
    }

    public function setFormatter(OutputFormatterInterface $formatter)
    {
        foreach ($this->outputs as $output) {
            $output->setFormatter($formatter);
        }
    }

    /**
     * Returns only the first one
     */
    public function getFormatter()
    {
        foreach ($this->outputs as $output) {
            return $output->getFormatter();
        }
    }
}

Then you can use it in your application

$application = new Application();

$application->add(new MyCommand1());
$application->add(new MyCommand2());

$output = new MultipleOutput(array(new StreamOutput, new ConsoleOutput));

$application->run(new ArgvInput, $output);
