There is a workaround for this. I think it can be found in the manual somewhere. For sure there are some posts on it here in the forum. Here it is how it works:
- set up two question groups. One with the first 10 questions, the other with the rest. All questions must be in the same "randomization group". What happens now is that those 50 questions randomly show up on any position of an the 50 questions. This means the 10 questions in the first group get "randomly drawn" from the pool of the total of 50 questions.
