There isn't an OEM switch to do that.
What I would recommend is using a blank button spot to the left of the steering wheel to mount a switch. Have this switch operate the dome light. Tap into the fuse box that controls the dome light (if that fuse only operates that dome light) If that fuse operates more then that, run a wire to the + of the dome to the switch.
Just saying you could make something work :Banane36:
