Harmony Hub Device Commands ST Integration

I have a physical Harmony remote.

Logitech Harmony Elite Remote Control (915-000256)

I want to press pause on the remote not on the touch screen to also initiate a light turning on. I know it can be done with an activity, but can it be done with the physical button being pressed?

Does anyone know a way to either convert an IR command (pause) to Z wave (light) or add that capability?
