Randomization (case 21082)

[queens]

I have 8 items in a questionnaire, 4 are positive and 4 are negative and there are two specific things I am seeking answers for:

1. I want to have each participant receive 4 of the 8 items, in a random order - is it possible to do that?

2. Assuming 1 is possible, I also need to ensure that each participant receives 2 positive items and 2 negative items. Is it possible to do that in medialab?

Thanks so much!!!
