I am not part of unipark and I am not sure that I understand what you want to do? What do you mean with “redirect links”?
If you want to end the questionaire early/before the last page because of a met condition or something else you can insert a final page (page drop down box at the top and then choose final page) in the condition. After that you have to adjust the properties of that page (click on the newly created page, then choose properties on the left) and adjust the dispcode field: the options there are completed, custom completed, rejected (quote), screened out and custom screened out.
