Restricting metadata from being importated into a project

Hello all,
still very new to Qualtrics, so please forgive my Qubie questions. lol. Can you restict a user from being able to pull specific metadata fields from the directory when importing participants for a project (survey)? We would like to allow user to create their own suveys, however, would like to restrict the ability from pulling some of the personal data we store in the directory. (e.g. Age, Date of Birth). Can a user have the ability to import participants from the directory but not import all metadata?
Thank you
Maureen
