Effects output to new track

A few years ago, I recall being able to add an effect to a track, but to have the output of the effect end up in a new track - effects only. This was helpful with delay and reverb, where I could adjust the amount applied during the song without messing with the original dry track. I can’t figure out how to do this in v3.5.x. Help appreciated.

There is the “Wet Only” option for Reverb, but not for Delay or Echo. I posted the request to add this option in the Feedback channel.
