Mixing two parts together
I wonder if it is possible to mix the notes of two parts (in this case a piano part) together on one stave without having to do it manually.
I have tried the usual New score and copy and paste, but that does not seem to work, I have also tried to add 2nd voice, no good...
It concerns very simple parts, an example is attached.
Please ignore the bottomline, I was a bit too quick when taking the screenshot.
It is about the two top lines which are a piano part.
Hope it is possible.
Thank you in advance.
