Going to have to throw this one out to the charity of the power users.
I have nothing from CA Support to share - we'd love it ourselves, to be honest. The Services guys are the most "hands on" with this. Everyone learns by writing their own notes.
That's the point of this Community - so I applaud you for asking. It's a place to start and hopefully the contributions for SPL will come over time.
Thanks, Kyle_R.
