How do you build a constructed list based on a predefined list?
For instance, I created a predefined list called "Custom1" and I populated it with "Product1", "Product2", and "Product3".
I want to make a constructed list based on these values.
i.e. if Custom1 == "Product1", add certain labels to the list.
These predefined list values are based on the respondents' product purchase, which is already recorded before the survey has begun.
