NRaas MasterController has a Focus function that focuses the game camera on the sim selected if they are somewhere on the map in the current world. It is available from the relationship panel if you also have the RelationshipPanel mod.
Will that suffice?
Edit: Pfft sorry, suffering from mod overload. You can also right-click on the sim in the RP and the camera will focus on them if they are in town without having to root around for the Focus command.
