It’s one rod with two hook tracks. One for the vinyl curtain and one for the decorative curtain.

No such thing. Your option is to hang a rod at the ceiling level for your outside decorative curtain and another at the standard level for your vinyl. Your decorative curtain would always be all the way across the top rod but draped onto the wall with a regular drapery hook on one side. Your vinyl would be pulled across only when you are showering.
