We want the possibility to send multiple unique personalized links to the same recipient without unsubmitted answers being saved across the different survey links. When we send more than one personalized link to the same user for them to evaluate multiple items from a custom table (one item per link), their answers are saved up to 28 days when the user doesn't submit (which is good), but the answers are saved across the unique personalized links instead of being saved only to 1 link.
