Replacing single switch by a dual one

Hi!
My bathroom has a light above the vanity, as well as ceiling light/fan. For now, they are both controlled by the same single wall switch. I would like to replace i by a dual switch so that we can separately control the vanity light and the ceiling one.
I attached a picture of the wiring.
One white wire from the left and two white wires from the right are all "attached" together with a cap.
The left red cable and the black right cable are attached together and connected to the switch.
the left black cable it connected to the other switch connector.
Does it look like it can easily replaced by a dual switch or will it need to run some new cable to be able to do it?
Thanks!

That's good news. It means power probably comes in at the switch.

The left red cable and the black right cable are attached together and connected to the switch.
One is probably the vanity light the other the fan.

the left black cable it connected to the other switch connector.
That is probably power in.

On the duplex switch power in goes to the tab side and the tab remains in place.

On the other side of the switch remaining black to one screw and red to the other.

Whites are left as is. I'd suggest using a meter to verify the single black is power in.

Your diagram for separate control of the fan's light and fan motor. In my instructions both are controlled by the same switch.

My post #3 contained an error please reread. See third quote.
