angularfire2 database list multiple update at once

Question

I need to update a database list multiple times as shown below.

Is there a more efficient way than calling database.list('path/to/').update(key,value) multiple times? Does it have an effect on the performance?

This is what I'm currently doing:

var newNode = {};
newNode[appointmentUid] = true;

this.database.list('/appointment/users').update(userId, newNode);
this.database.list('/appointment/users').update(worker_uid, newNode);
this.database.list('/appointment/users').update(client_uid, newNode);
this.database.list('/appointment/users').update(patient_uid, newNode);

you can use ref ... update with the object notation to update multiple elements at once. Ex from the doc :

let newValues = {
  "userId": newNode,
  "worker_uid": newNode,
  "client_uid": newNode,
  "patient_uid": newNode,
};

firebase.database().ref('path/to').update(newValues);

Thanks @Miam84, but I think there is not that option in Angularfire2

The questioner has asked multiple updates for AngularFire2 and not the firebase JS sdk.
