Switches are on/off and dimmers dim and aren’t switches so that’s an odd application. Maybe you could use a dimmer setup as a keypad only (not controlling the load directly). Use some sort of high voltage relay wired to the load that has a trigger trigger input. Using a relay off the controller as that trigger input you might be able to use some programming via a tap and then push and hold on the keypad? It’s just a guess but might be possible. I would call in to support.
