We have our own Satis repository, we can store there our own dependencies. This works fine.
But if a developer uses a package that is not within in our own repository, then Composer will fetch it from GitHub through packagist.org (as a fallback).
But we do not want to be dependent on packagist.org. All dependencies should be downloaded from our own repository.
What we like to know, if its possible that Satis download a package from Packagist, if it is not locally available yet, and then store it and add it to Satis own repository automatically .
This way we do not have to manually add the dependencies to the Satis repository.
