Hello,

Wondering if anyone can help. For my survey I photoshopped 4 headphones(2 low design - 2 high design) with 4 different brands (2 low brand strength - 2 high brand strength). Which gives 16 different headphone - brand combinations. For the survey I want people to see all the different headphones and brands only once in a randomised order. Therefore they will see 4 different combinations. 

In the survey all the combinations are set up as 16 different blocks with a photo and question. 

Furthermore if 1 low design headphone is linked with a low brand strength the other low headphone should be linked with high brand strength.

Example: if for the first block low 1 is linked with brand A, headphone low 2 should be linked with brand C or D. Also brand A will be excluded for the next 3 blocks. See figure for overview.

My question is, is this possible in Qualtrics and if yes,  how could it be done?

Thank you for your help!
