Apply note input 'N' for Staves

2) In order to write composition like orchestral music, we often need to change NOTE symbols/value (crochet, minim, etc.) on more than one Staff in the same beat (the notes position are in one line, vertically) with similar NOTE symbols/value. I think it will be more effective if we could select the notes on instrument Staves (all note in the same vertical line) and than all we have to do is just click the Note Symbols with the 'N' button. It's much faster than change the NOTE value note per note.
