Cubase 12 Staff Notation Editor & Genos

Has there been any improvement with the Staff (Score) notation editor in Cubase 12.
Also, can Dorico 4 be used to take a Cubase 12 midi file for more note editing and then be inputted back to cubase 12? The midi file would be created by the Yamaha Genos Arrangers Keyboard. In this way it would give more flexibility to the arranger to change notes while sustaining the original articulations of the Genos. your replies are appreciated
