We have multiple contact lists for each of our maropost accounts. The same email will be on several of those lists, because we use them for testing purposes. Currently, the lists are all connected so if the email address alredy exists in one list and you add it to a new list, it'll automatically pull in whatever contact details there are in the other list, even if you intentionally left some fields blank. I need the ability to have different contact details per list (ex: first name). This will let us thoroughly test the emails before sending them out.
