Writing in multiple parts simultaneously?

I've often found then when I'm writing stuff for open score and piano that after I've imploded parts to the condensed piano score, I want to make some edits to the parts, and so obviously I'd have to to edit both the piano score and the open score.

So I wondered if it would be good to be able to link parts together. Perhaps when the user writes in one part, there's a feature where one can have it automatically print the same thing in another? I'm thinking of a feature where you would link something like Soprano to voice 1 in the condensed treble clef, the alto to voice 2, the Tenor to voice 1 in the bass clef and the Bass to voice 2.

It would save having to make edits to both parts, and also would eliminate some of the messiness of using the implode tool.

What do you guys think?
