An actually useful "Add Instrument Track" Command for Macros

So the recent 3.5.3 update added the ability to specify a plugin or FX chain (and even a preset for it, nice!) in the "Add Insert to Selected Chaels" command. Can we please get the same thing for "Add Instrument Track"? Right now, you can specify a name for this, but not an actual plugin, meaning this command saves you virtually no time, since you still have to drag-and-drop an instrument from the browser if you want the instrument track to have, well, an instrument.

Having the ability to create macros that load up specific instruments (and even specific presets for them) would really help my workflow, since I could map that to a hardware button press and instantly have a new instrument ready to play.
