In a loop? Not really. With an effect like a delay with feedback, or a reverb with a fairly long tail, if you try and turn off the send right near the end of the loop, audio that had been sent to the effects prior to turning it off (or quickly dropping the send fader) will still be present in the effect when you turn it back on at the beginning of the loop. Same thing if you try it with the return. This method still suffers from the same problem inserts have in this application. Automating it won’t help either. What I described above will solve the OP’s problem. Yes, extra steps, but it will effectively quash the end of loop delay/reverb spill-over back at the top of the loop.
