If you don’t need correct playback and are happy with the reversed l.v. tie solution, here’s a zip file with a folder that you can drop into your user scripts folder. It contains 6 scripts – creating short, medium, and long backwards l.v. ties above and below a selected note. (The number in the script name refers to the length of the tie in spaces.) Just select the second ending note where you want the tie and run the appropriate script.
