Two Family Home Installation

Hi everyone, New to the Ring community and was looking for suggestions on the best way to install my new Ring Pro. I live in a two family home with two separate doorbells. Each doorbell has the two wires connected to the screw but both pairs of wires eventually run into one wiring into the wall. I can remove the wiring from my bell and connect the Ring, however I would have to buy a new single bell and reattach the other home's wiring. However this would be exposing the wires as it is just sourced from one hole in the wall. Any recommendations? TIA Tony
