Tap Tempo Control for Hog 4 PC

Im looking for an easy way to have "tap tempo" control of cue lists from a Hog 4 PC setup.
I know on a console, you can hold down the Choose button of the fader and use the Play button to change the rate of a chase.
Does anyone know of an easy and inexpensive way of accomplishing this without a Hog fader wing?
I was thinking about using an X-keys XK-12 Jog & Shuttle but I'm not sure if this can be programmed to an encoder.

Any thoughts?
