I've been wondering for some time if it is possible to take responses from multiple previous questions and insert those responses into a multiple-response question later. To explain what I want to accomplish, I give participants multiple choice questions to select their religious group, their racial group, their political group, etc (say about 8-10 different categories). What I want them to be able to do later is see a listing of the groups they've already chosen and pick 4 of them (the ones they consider important to them).

So far I've settled for presenting their answers back to them in a set of fill-in-the-blank questions and asking them to type in 4 groups that are important, but this causes problems with spelling, repetition, and unusuable responses.
