如何从另一个包加载翻译

I have two bundles: AppBundle and AnotherBundle.

I have to translate a string in AppBundle:

{% trans from 'anotherbundle' %}anotherbundle.string{% endtrans %}

The problem is that when I extract the strings to translate with JMSTranslationBundle, the file anotherbundle.en.xlf is created inside the AppBundle/Resources/translations directory while I want it to be created in AnotherBundle/Resources/translations directory.

To extract the translations I use this command:

bin/console translation:extract en --config=app

and the configuration I use is this:

jms_translation:
    configs:
        app:
            dirs: ["%kernel.root_dir%", "%kernel.root_dir%/../src/AppBundle/"]
            output_dir: "%kernel.root_dir%/../src/AppBundle/Resources/translations"
            ignored_domains: [routes, FOSUserBundle]
            excluded_names: ["*TestCase.php", "*Test.php"]
            excluded_dirs: [cache, data, logs, web]

How can I make JMSTranslationBundle extract the translating string into AnotherBundle directory?

I always leave the options blank and the translations are available in every single bundle I use. I only have to refer to the domain.
