"doubling up" staves in score

There has been some previous discussion of this in an earlier thread:

As for pitch before duration, I’m afraid there won’t be any chance of us getting this in before the first release, but I wouldn’t rule it out completely for the future. I would ask that you do at least give Dorico’s note input method a try before you declare it unusable. I believe you can teach old dogs new tricks — I find note input into my previous scoring program (I imagine you can guess which one it is) almost impossible now that I have fully assimilated Dorico’s method.
