As Jazzmammal points out, fully fledged notation programs can cost as much as an Ultrapak.
So, in fairness, we really can't expect a top line notation capability within BIAB for the money they charge for the basic program.
But I GET IT that issues like this are frustrating.
If I were PG, I would create a Premium Add On notation capability and charge for it...just like they charge for RealTracks...if users WANT enhanced sound. Ditto for enhanced notation and for the same reason....COST.
Just my 2 cents.
Best,
Jim
