2 Caseta switches, (seperate circuits) get each switch to control both switches ?

Greetings, I have 2 separate circuits, and a Caseta dimmer in each, Is it possible to get ether switch to control BOTH, itself AND the other switch ? The House is wired for a stairway light at the top of the stairs, AND a separate circuit at the bottom of the stairs, NO i do NOT want to open up the walls to join the circuits. using 2 pico remote would mean pressing 2 switches at each end.

Thank you, in advance.

If the 2 Caseta dimmers were in the same box you might be able to combine them.

You can assign both dimmers to a Pico. You would only need to press a button on the Pico to turn both lights on/off.
