SecuritySuite - SuiteCRM and CE Teams

Dear Sirs, I have a following scenario, I have 2 users in 2 different groups. Each of groups are having different rights on certain Account module. Filter User List is on, as I want to be able for users only to see their group members. Now , there is a situation where one of the users from 1st group needs to see only names of other users from 2nd group and not to inherit any rights from 2nd group. My though is that when you add that user in 2nd group and mark "not inherited" as on that it would do the job, but the rights are still assigned and they inherited all rules just like any other user from 2nd group. Thank you very much and looking forward to your reply. Best Regards, Slaven.
