Here you go - I only did the first line. While I think I’d get faster eventually, doing the whole lot would definitely be a grind.
Have updated it too to sort the metronome mark and a couple of other bits, like one of the trills whose natural wasn’t quite notated in the same way.
Engrave mode is truly remarkable. Only a small amount of fakery was needed here - I replaced the stems and used lines to create the strange beaming in the soprano part. It has to be said that whenever I edited anything remotely nearby the lines, they jumped position and I had to put them back into place again numerous times.
