Bluesound and Spotify Family

[Aneda]

I have two Bluesound Node players. Mainly it is my iPhone being used as the remote control.
Today it is only me in the family having a Spotify subscription, meaning that same music must be played on both Node-players and if I want to use the iPhone for music the music in the anode players stops.
Question: Having two or more accounts may of course help. But having different accounts on the two Nodes, will I still be able to connect them together and play same music on both? Having different account on the iPhone and the Node, will the iPhone still work as a remote control for the account on the Node?
