One thing I started to try was randomizing group order and then hiding the groups after the 6th group is presented.
I wasn't able to set a variable that would correctly count how many groups had preceded a particular group. To use that approach I initially set the variable to 1 in a fixed group at the start of the survey. Then I added an equation in each group that added 1 to that constant. I set relevance equations for each group to condition on that variable to remain below 7. However, I couldn't get the lime to count up to 7 as hoped.
