it is possible to create lists in a way that when people edit their preferences they do not see those lists as options to get in?

ie. i had to import a contact list from previous campaign system  from which we got their consent through the previous system.

did want to avoid doble optin confusing message

we created a list with implied consent settings

now this list that is purely an import of previous system shows up within the list of option when clicking to preferences

how can we hide this list from the edit preferences  message?

thank you very much
