How to randomise the order of response options to a selection question? (answers in German also welcome!)

Question

I am aware of the option "Shuffle/rotate randomly" but it's not what I'm looking for.

Say I have 5 response options. What I want to do is to randomly show participants either of two specific sequences, namely either 1-2-3-4-5, or 5-4-3-2-1. I don't want 2-3-4-1-5, or 4-3-2-1-5, etc.. Is there a way to do this?

Thank you in advance!

Please create a random generator (e.g. RG01) with codes, and use this PHP code to display the question (e.g. AB01).

if (value('RG01') == 1) {
    question('AB01', [1,2,3,4,5]);
} else {
    question('AB01', [5,4,3,2,1]);
}
