I think Delta has one. We only needed 2-way, but I'm sure it came 3-way also.

Danze Single Handle 4-Port Shower Diverter Valve,
Product# D130000BT will do this.

Are you looking for a single diverter for the three fixtures or one that can also control the temperature? There are multiple options for the first, a lot fewer of the latter.
Kohler has a number of trim kits for a stacked thermostatic valve/diverter unit, but each has two handles, one above the other. I linked one option that seemed most similar in style to the one you posted, but there are other options with mor transitional or traditional styles.

I have a Grohe 19825 that combines one lever for diverting between shower and tub spout, and another lever to control the temperature.
I like it a lot - just one valve and trim for everything!
