Milisecond Delay on EACH CHANNEL

On the X32, it is possible to route one channel into the next, stereo pan them, adjust levels, and then apply a delay to the second channel ON THE CHANNEL STRIP without wasting an effects rack, but this isn’t possible on the X Air series and would be really nice as this is an old studio trick that’s not only nice on acoustic guitars but also guitar cabs, vocal doubling, etc…
