audit table access through specific roles

Does anybody knows if it is possible to implement, using standard Oracle auditing procedures, a way to audit users acessing specific tables , but only if they have been granted access to it by a specific role or roles?

I mean, audit users accessing table A , who have been granted access to it by the role A_READ, A_ALL, and not users who are accessing table A who have been directly granted access on A, or through another role which should not be monitored

Thanks
