How to create backward-relating ties?

Hey folks,

I’m engraving this Beethoven example, extracted from Read 1979. Any updates on how to create these “backward-relating ties” that are ties from before the first measure of the example?

Best suggestion that I could find was from PianoLeo, but fighting with the weird reverse flips of the l.v. is a bit of a chore https://www.steinberg.net/forums/viewtopic.php?t=146216

Thanks!

You could fake it by having the “start” of the chord be in a different frame, on a page that you don’t print.

You could also create stemless, flagless, full-scale, invisible, muted grace notes and tie them. You’d probably want to adjust the note spacing so the ties look appealing.
