GAUGE multi chart per series problem with gauge title/subtitle

Result i need - view sumary and charts on same page where charts are above 3 col per 3 lines

And… i can do it without problem - problem starts with using chart named gauge - its great solution for explain high agregated data but it have limitation that prevent use it for multiseries data charts

Its really simply problem - there is title of chart where chart display field of grouping name and that field is enought if u want only one gauge from your dataset - but if you want few of them grouped down by series thare is problem becouse gauge is not showing subtitle where we got info about series used to group/filter data.

We need or scriptcase update (in mine opinion its simply bug - somone forgot about that feature) or if anyone had same problem and soved that (throu esion variales or any other way) please share your knowledge.
