I am not sure that I understand the exact requirement that you have, but I could suggest that you take a look at our "Aggregates
" demo and see if this is what you are looking for:
If your requirement could not be achieved with the aggregates, please provide some mock-up or screenshot of the final result that you are aiming for.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
