Best way to wire bathroom exhaust light combo

I have a bathroom light/fan combo, would like to wire it with two switches instead of one.

Its pretty short about 10 ft from ceiling to switch location. The cable is an old cable with 2 wires only so i can not hook up the second switch for the fan.

What is the best way to approach this? Can i remove the fan, and stick a new romex 3 wire cable and try to fish it into the switch location? or switch to fan location?

Maybe just add one wire instead of a new romex cable?

Making holes to help isnt possible, there are tiles along the walls, so after the ceiling i would have to remove the tiles. I prefer not to.

Whats the best way?

A 3-wire cable is the best solution. The old switch box can be removed for fishing in the wall. If you have an unfinished attic above then a new cable is not that hard to run. If it is too hard you might consider a remote control.

Note you can not just run a new wire. Code requires all the conductors to be in the same raceway (sheath or conduit) to reduce the possibility of overheating.

If the circuit is not grounded it should not be extended.

If it is grounded you would run a new cable between the switch and fan after finding out where the power gets to the switch.
