I have an additional question:

Is it possible to assign some kind of picture to a specific choice task?

For example: I have 40 different choice tasks in total (4 questionnaires each with 10 choice tasks). I would like to assign specific pictures with information to each of the 40 choice tasks.

The assigned "picture" would contain additional information for all the tasks in this specific choice task (the picture should be above the tasks). Something like: Choice task 1 of 40 has the following information included in the header: "imagine a sunny day", choice task 2 of 40 has: "imagine a rainy day". choice task 28 of 40 has: "imagine a windy day".

Would this be possible?

Thanks in advance

But I'm not sure how to implement this for more than 1 fixed questionnaire. If I would follow your approach, I could for example add 7 more lines to assign text to a total of 10 fixed choice tasks. My problem is that I have a total of 4 fixed questionnaires (with 10 choice tasks each). This solution would only work if the "text-information" is in every questionnaire the same. But unfortunately I would need 40 different texts/images, because every one of the 40 choice tasks are different.

So basically I have 40 different fixed choice tasks, spread over 4 questionnaires in total, each of them needs specific information.

I really don't know if this is possible. I'm thankful for your help.
