key notes

would it be possible to include a feature that I would call "key notes", working like the following:
- select on or several bars in one line
- select "insert key notes" from somewhere
- choose an instrument of which the key notes are taken
- insert those notes in small execution into the line
(with or without dynamic, articulation, lines?)
- insert the instrument's name as text of the line. (Strg+T)
- refresh on demand (perhaps F9?)

this would take the programm one step closer to the use of the same document for full score and parts. The different storing of concerns of layout (lines, dynamic, etc.) is already contributing valuably!
