can one user have access to multiple policies?

my employer would like me to create separate policies for different units.
but, they would like some individuals to have access to more than one
policy. for the purpose of viewing multiple contact lists. can this be done?

or, is there a better way of doing it.

the functionality of the profiles is the same throughout.

the purpose it only to restrict users to certain contacts and at the same
time give an individual access to multiple lists.

thanks in advance!!
