There are currently two methods to input data into demand diagram, manually and import via a DDG text based file. The DDG import method is highly sensitive to the format and archaic carried over from InfoWorks WS era. A suggestion is to create import from a more conventional grid style or CSV format to make ease of importing large data set easier. The ability to open the CSV in WS Pro and select the pattern title, time, data and other coefficients before import will be great improvement over the current approaches.
