It would be an incredibly useful, time-efficient feature to be able to drag and drop an entire instrument track, including the loaded instrument and adjustments, channel plugins, presets, etc into another song, rather than just an instrument's "event".
I.e. Drag and drop a Kontakt or EW Play instrument into another song and have the mic, reverb, and all other plugin-contained adjustments be there so that the track is an exact duplicate. Something like "Duplicate Track (complete)" but between songs/projects.
