I also think this would be a great feature! You can always take a look at how Serum is doing it in SerumFX for some inspiration.
@rafa1981 I do it in a similar way, but rather add another track and do some routing, similar to this [Tutorial] Elektron Overbridge as FX in Reaper - YouTube In this way you don’t need to add any additional VST:s, just an extra track and some routing.
