Anyone know of any specialist management mods?

[BARBEERIAN]

I'm wondering if anyone knows of any specialist management mods. A few searches didn't really find anything other than mods that add new types of specialsts. Basically what I'm looking for is something that would allow me to 'disable' certain types of specialists in a city. For example: I don't want my Commerce City's governor assigning anything but Scientists or Merchants when the city grows (instead of stupid spies everywhere!) so the mod would let me disable the other types of specialists.
