z-wave push button

Guys, I am trying to fogure out a way to build a base for some lamps and recess a button into the base of the lamp that can control my z-wave bulb or plug in module, etc. What I would like is push on, push off and hold for dim.

Has anyone seen anything like this? The closest that I have seen is either the Aeotec panic button or the Aeotec dry contact sensor, but that would just give me the ability to do on and off.

Any thoughts here?
