Not sure if I completely get your problem. Your first need to setup the cluser thing, which does nothing at first.
Then, in the General section, under Indicators, you need to assign one of the things of the panel to this cluster thing, I use the outer edge for example.
(This is for my druid setup, don't have a shaman on hand right no. For Chain Heal, should be chained, then how many jumps chain heal does and the chain heal spell)
(I use the inner edge on mouseover, so it immediately shows me who is eligible to be hit by Wild Growth, even if it's more than 6 people, it is an intelligent heal)
