I have a block with 2 groups + 8 questions in each, how can I show a random 5 questions from each group?

Question

Hi, not sure if my question will make much sense but if anyone can come up with a solution please let me know.I’m new to qualtrics and most stuff I have picked up as I've been making my survey but here's the one thing that's stumped me.I have a block which has 21 questions and these questions are part of their own ‘groups’ (they're not grouped or anything in their blocks though, not sure if that's possible?)group 1 has 5 questions which I want participants to see all ofgroup 2 has 8 questions and I want participants to see a random 5 of themgroup 3 has 8 questions and I want participants to see a random 5 of them. I have worked out the advanced randomisation tool, but of course if I put the 16 questions into the random subset part and told it to generate 10 questions it could end up generating 8 from group 2 and 2 from group 3 I would like the questions to be presented on the same page and randomly mixed up if possible. Hope this makes sense, if anyone has a solution for this please let me know.

In a block prior to your 21 question block add 2 multiple choice questiona where the choices are the group 2 and group 3 questions. Use advanced randomization to display 5 of 8 choices in each. Hide the questions with JavaScript. In your 21 question block add display logic to the group 2 and group 3 questions based on whether their choice was displayed in the corresponding hidden question.
