Great question, and an important feature request for sure.
This would help EDM producers, tune the claps, etc...
Although not the answer you're looking for, a VST that has this feature is: ValhallaDelay.
On the bottom left, turn the STYLE knob to "Dual", which opens up the 2 x options "Delay L" and "Delay R" in the 2nd column.
Finally, Logic Pro seems to have this out-of-the-box, as in the "Simple Delay" below.
