I don't think so. Adding other stencils to Glissando.stencil (without modifying the original) works fine, even for broken cross-staff ones. Alas, I currently do not know a way to get the needed values for _placing_ those additional stencils, if the cross-staff Glissando is broken. In this case Glissando is bound at least on one side to NonMusicalPaperColumn. And, the different staves for start/end of the Glissando may come closer or not. There is some code in line-spanner.cc dealing with the problem. Though, with my lack of cc-knowledge I do not understand enough to redo it in scheme. Granted, there's https://gitlab.com/lilypond/lilypond/-/issues/6551 but I'm not attempting page-breaks at the current state. Cheers, Harm
