@tsullivan Can it also be done on the Elastic.co cloud?
I really don't know. You and a colleague have been posting in another thread about trying to do this, and according to messages there, you are getting this error:
{"ok":false,"message":"Unknown cluster."}
When you use Kibana hosted in Cloud normally, you are talking to a proxy, and that proxy has headers that it sets, including one for the cluster_id. I don't know enough about this to know if your proxy might be preventing the Cloud proxy's header from persisting.
