Can I pair a Pico Remote Control Switch with a Caseta Wireless In-Wall Neutral Switch (PD-5ANS/PD-6ANS) that is wired to a Mechanical Toggle Switch in a 3-Way lighting configuration? Once paired can the existing 3-Way system be operated as a 4-Way lighting system with the Pico Remote acting as the 3rd switch? The existing 3-Way lighting sys is wired as shown on page 35 of Caseta Wireless Advanced Installation Guide (https://webapiaw1proddat01st01.blob....structions.pdf).
