This is because moodle will report the same question(s) as two individual categories. I would like to get a global idea of what training people would like and as such need to avoid asking the same question multiple times.
The reason I am looking for dependencies is because I don't want to ask every person taking the survey every question but rather tailor the questions to a specific level. Unfortunately the questions have relevance in trainee and level I categories.
I have found a basic work around but if forces everyone to be asked a base set of questions then at the end expands on that based on if they are certified at all.
I think the option for multiple dependencies would be a nice features in the feedback activity and allow a more tailored or branched set of questions.
