Hi Mark, > Oh, goodness… This is like a Plato’s Cave moment for me in Lilypond. I honestly can’t believe I haven’t had this in my quiver. Unless somebody (Jean? David K?) says this is somehow a sub-optimal implementation, I am using this in everything from now on. Thank you so much! Kieren.

Hi Kieren, It's one of the reasons I first suggested the "anchors" idea over 13 years ago (see https://lists.gnu.org/archive/html/lilypond-user/2009-07/msg00498.html); when I picked up the idea again (search for "addAt"), that thread eventually revealed the edition-engraver, and may have led
