+100 to this feature as it really does make Notion less useful to be unable to preview a score with one-off repeat parts -- a shame since it otherwise handles repeats, DS/DC al Coda, fairly well. But what's the help of this if I can't hear it as written?
The workaround suggested is to "unroll" the score, ignore all performance markings, and resort to copy/pasting -- not great -- that sort of thing just creates extra work and frustration over time. I'm a developer by trade and we follow the principle of "Don't Repeat Yourself", and hopefully PreSonus believes this too. So, if you wouldn't do this in your code, why make me do it in my score?
Furthermore, with all the focus on add-on instrument packs and sound quality it seems strange that they would leave out such an obvious playback feature. I'm much less likely to want to sink any money into this ecosystem if the base software can't handle the playback structure I need.
