The feature allows you to take the results of multiple scenarios and format them in a single Excel report. You may select which scenario results to include (only those scenarios with results already computed and being shown in the choice simulator menu may be selected). You may also select one of the scenarios to be the base case reference scenario to which the others will be compared in the summary page.
There is also an option at the bottom of this dialog to include the summary page. The summary page will show each scenario as a column with the product labels as rows. The product labels that match between scenarios will be matched and placed on the same row for comparison across scenarios.
