Can you stop a workout session from the phone?

I've managed to get a workout started from an iOS app, using -startWatchAppWithWorkoutConfiguration:completion:, after some trouble, but I can't find anything about stopping the workout from the phone. Is this something that's possible?
There is no way to do that through HealthKit APIs. You can use WatchConnectivity to send a message to your app on watch telling it to stop the workout session.

Is this still the case?
