Fan/Light Combo Controller

I’ve seen this mentioned in a couple of posts, but it would be great if “someone” created a z wave device that hooks in to the fan speed controller and lighting controller similar to the INSTEON Fanlic controller. This would mean all I’d need to get my combo fans up and going is a z wave switch, and that controller instead of going through the hassle of cutting a three gang box to fit an extra speed control switch in.

I’m not that versed in electricity to try making the project myself, but perhaps there’s a way to makeshift the control now?
