the possibility to use service / host labels eg. groups in the graph designer

ulterior motive
I have 30 hosts with the same service and simply want to bring a metric of these services into a custom graph.
so the list in the graph designer will be longer than my monitor upright ....
and it would also have the advantage that the graphs would be more dynamic and require less maintenance

not to be underestimated with ~50 custom graphs
