Eligibility profile with multiple criteria

Summary:

Hello,

we are trying to create an eligibility profile for HCM Communicate, in order to have a group of e-mail recipients, consisting of two separate subgroups (let's name them Group A and Group B).

By testing, we managed to create two different eligibility profiles: For Group A, by using the Person Type criterion and for Group B, by using the Business Unit and a User - defined criterion.

My question is: how can we include both criteria in the same eligibility profile, without having conflicts or overrides? The reason why I'm asking this, is because people who belong to Group A can be working in Business Units, which are not listed in the case of people in the Group B.
