Is it possible to randomize the order of Groups in Quizmaker '13?

This thread is two years old but I'm wondering if Articulate will ever add this to their roadmap or if anyone has come up with a workaround? It definitely doesn't appear to be possible with  question banks in Storyline so I pulled out Quizmaker thinking this feature might have finally been added but I still can't figure out a solution.

The original poster was not asking how to randomize questions within groups - re: the support article that was provided - he was asking if the randomized pulls from each group can be further randomized. I have the same need.

My project is an exam prep/study guide course for learners in a particular profession. The real exam they will eventually take has a set number of questions assigned to each topic (pulled from a massive pool) so I'm trying to replicate that experience.

I have 10 groups of questions, each one covering a separate exam topic. Each group is set to randomize and include a sub-set of the questions. I'm good up to that point. But when the quiz is published, there is no randomization between the sub-sets.

In other words, if my first group of questions is about Topic A, and I'm pulling 5 random questions from that group, the first 5 questions in any quiz attempt are always going to be about Topic A. Even though they are going to be random questions, it will eventually become obvious to the learner that the correct answer to the first 5 questions is going to be Topic A-related. And the next 7 are going to be Topic B, the next 5 Topic C, the next 10 Topic D and so on.

This makes the practice tests much less rigorous and therefore less valuable to the learner.

If anyone has any suggestions, I would be eternally grateful.
