+Push Notifications v2 also supports specifying a name to the push tokens you register. By setting the optional `pushProviderName` param in the `addDevice` call you can support different configurations between and the device and the `PushProvider`.
+
+```dart
+firebaseMessaging.onTokenRefresh.listen((token) { 
+      client.addDevice(token, PushProvider.firebase, pushProviderName: 'my-custom-config'); 
+}); 
+```
