I finally (yes, finally) got my first "Own Five Top Level Businesses" LTW, only to find it's a major PITA not to be able to control the sims that work for you. I've run a pretty extensive search across MTS2 and MATY and come up with no solution.
Managers are controllable, so there must be some way that it could work, but knowing Maxis...
Is it possible to make employees controllable?
