Beside using different articulations of an instrument and modifying an instrument with automation, it would be nice to have also event instruments. In many cases an instrument fill or other ideas, instruments for just one part would be nice.
It is the counterpart of event FXs,you just want one part with it and dont want another track for it (you need many tracks)
Because the console routing is intependend from the tracks, you also can mix this instrument seperatly and you can also see it like the event FX in the inspector for further editing.
