I regularly want to group my lounge speaker to the stream playing in the kitchen. I hold the play button on the speaker in the lounge to group it, but it will group with another speaker say in the bedroom or a TV. I continue to cycle through the playing speakers until it finally groups with the kitchen. I would like to be able to set a preference in settings to select a preferred speaker to group to so that if the kitchen is streaming it will always group with the kitchen speaker.
