Arnie, that's a good idea...I know it sounds kind of like the "New World Order", but I usually to try to pair up those with the same duties, because you tend to get some inheirited traits for learning that way. However, once in awhile one will come along that has something completely different from his/her parents...or I will get one marked for "doctor," but it says he/she likes wood, or lifting, or swimming. Those I allow to "choose" their duties.
