I can calculate volume from level, but it's an extra step and requires that I copy the run results out to Excel. It's even more difficult if I have a non-circular tank. Please include tank volume in the tank results and in the "System Demand" report.
Note: You can directly report the volume in individual tanks already.
Howerver adding system-wide tank storage could be a useful new result field added to the System Demand report as suggested.
I have updated the title to reflect this.
