Hello,

in my survey I have two conditions: Participants in group A see 72 pictures (one after the other), participants in group B see the same 72 pictures one after the other, but paired with one other picture. Here, the 72 pictures should be paired with in total 8 different pictures - so out of the 72 pictures, 9 pictures are paired with one same picture each. The pairing of the pictures is predefined and is not randomised. 
For both groups, all the pictures are to be shown in a random order.

Is there a way to always combine 9 pictures with 1 picture?

Many thanks!
