Note input into two voices?

I know I can input notes onto two separate staves at the same time: can I do the same thing with voices on one stave? I can’t see it in the manual.

Workarounds are: input onto two staves and reduce; or select the lower notes and move to Down-stem voice (though this doesn’t handle Unisons well).

No, you can’t input into two voices on the same staff at the same time. It’s an interesting idea we could think about for the future.
