Query “System Demand” results for “totalized” volume

It is universally understood that “the area under the curve” approximates the total volume of water for each of the “System Demand” output graphs in InfoWater Pro. Although a “Totalizer” can be applied to a pipe, it is not currently possible to query the “System Demand” output for totalized volume. While a totalized volume can be approximated by hand using the System Demand Report, this would be unnecessary (and likely more accurate) if there were an option to have IWP tabulate Cumulative Volume for each time step (similar in function to a pipe totalizer), especially for Pipe Leakage.
