Attached is the wiring diagram for the knockout box in my bathroom. There is one switch that turns on the exhaust fan and lights together. My wife wants them on two separate switches. I cannot figure out how to do this.

In the knockout box, you can see the back of the hallway light switch plus three holes in the box for wires to enter.
Is it possible to separate the fan and lights?

The bathroom switch appears to be a switch loop because it has a black and recolored white. If true you will probably need to add a cable. How many wires at the light? How many wires at the exhaust fan? What are the connections?

 

I'm seeing the black (hot) wire going to the "bathroom switch." Then the recolored white goes to the "back of hallway switch." Then another hot wire to the hallway switch and then out to somewhere.

That can't be correct.
