This is exactly what you're looking for:
Pigtronix Products - The Echolution Delay
It's a pretty unique pedal because you can assign up to 5 additional delays all from toggles in quarter notes or triplets. I'll admit I don't own one, but I've seen videos of it and it will do what you want. I'll be getting in an Eventide Timefactor tomorrow and when I do, I'll see if it can do anything similar.
