I’ve personally tried the above video’s method but I have found it can be fairly inflexible to adjust and time-consuming to build. There’s also the free font AleBoxes, which I think is more flexible, but yes, it’s another workaround. I believe the team is looking at a way to make this easier in a future update. fingers crossed
In the meantime I actually prefer somewhat of a hybrid, I simply create a special repeat bracket/brace around the notes I want, and I then use the big long center line as recommended in that video above.
