At this time, Questionnaire Criteria is grouped separately from your other Criteria and cannot be combined. If you want the score for your Questionnaire to be considered under another Criteria Group, then you can:
1. Set the Weight Scaling of your Questionnaire to 0 (so that the Questionnaire score isn't counted).
2. Add a new Rated Input score under the Criteria Group you want the Questionnaire to be a part of, and have the total equal the same total from your Questionnaire.
3. Once the questions in the Questionnaire have been scored, manually enter that score into the Rated Input criteria under the other Criteria Group.
