Use Testflight but don't erase store builds

Is there a way to distribute test builds to testers without the app overwriting the release builds? Can we use Testflight for this or do we need to distribute it via an .ipa?

Im not sure this solution still works. iTunes Connect in your process is not allowing me into the Apps section.
