I agree with Dennis that it is not worth making a cluster if an array serves the purpose (Here, all elements are of identical type!). You can even customize the control so it looks exactly the same as your grouped boolean+decoration and thus duplicates your design when placed into an array container. In the attached quick modification (LabVIEW 7.1), you can select which boolean (1..8) to display on the right using a vertical slide. Modify as needed.
(Btw, your second attachment attempt is still in LabVIEW 7.1).
