That's why it's not there. Think it through. Why? Isn't there a way to run the return in parallel? If not, then yes, I agree. IF it can be run in parallel mode, though, then you could control output TO the return with a volume block before it (or similar), both in your 2nd path, and leave the rest of the signal blending with it so, whether or not you allow signal to go to the return, you still get your sound coming through the 1st path. You would have to set your reverb or delay pedals within the fx return (The actual pedals) to be full effect, no source, for it to work properly... otherwise your volume would increase when you sent signal to the fx return since the fx return would also contain the initial sound of your instrument and it would sum with the 1st path (which doesn't leave your helix box)... assuming your pedals don't invert polarity, in which case it'll nullify and make it horrible sounding or nearly silent, depending on phase accuracy.
