Smoothly fade between cues when an effect is adjusting parameters such as trail, grouping, etc.

When you modify channel grouping, trails, or any other aspect related to channel redistribution within cues, the effect abruptly snaps, irrespective of cue or effect timing. I desire the capability to create a seamless fade between changes, allowing the outgoing effect to fade out over a specified time or cue duration, while the incoming effect gradually fades in likewise.
