DCE internal calculation

Hi SurveyEngine support team,

I am building a DCE which requires internal calculation between attribute levels. For instance, I have various types of travel time attributes, along with a distinct attribute named “Total travel time,” which represents the cumulative sum of all travel time attributes. Similarly, I have diverse price and discount rate attributes, and based on the levels of these two attributes, I intend to compute the discounted price for each scenario.

I’m uncertain whether I can directly derive the values of certain attribute levels and utilize them to calculate another attribute level within each DCE scenario. I would appreciate any suggestions you may have regarding this matter.
