Please add CC Controller options in a Simple Instrument Track.  When making a full orchestral arrangement with sample libraries like EWQL, it is often necessary to automate Expression and other CC Controller information, but the only way to do this is by creating separate MIDI and Synth/Audio tracks for each instrument.  This results in a very cluttered workflow when you consider that each instrument has multiple articulations.  And since you can't create nested folders, it's difficult to keep everything organized.  If Simple Instrument tracks allowed for CC Controller automation lanes (automating controller info in the PRV is kind of a pain in my opinion), it would no longer be necessary to double each track.

Can't you right click on the SI track and split it into an audio a midi track and then rejoin them when you're done?
That is a good idea though, if the software can know the MIDI CC's and use them on the SI track.

Huh, never thought of that!  While it would be more efficient to allow for both Audio & MIDI automation content in a Simple Instrument Track, at least your idea would clean things up a lot!  Right now it's just a mess with all of those duplicate tracks!  (I'm SO glad Sonar adopted track colors a while back!)
