Odd question: 3-handle thermostatic valve?

[abernat]

My wife and I like the "classic" look of a 3-handle valve, but I'd prefer to have a thermostatic valve. I could swear that I have seen a valve that provides both, with the handles controlling temperature, pressure, and showerhead/tub instead of hot, cold, and showerhead/tub. Does this ring a bell, or am I just off my rocker?

Many thermostatic valves could add a third control for the divertor. Many have them stacked vertically, though, not horizontally.
