Hi @kelvynchin, I’m afraid it’s not possible to do that. The reason is that a lot of the way Finale displays things is not stored in the .mus file but handled in program code which is not accessible to Steinberg.
When Finale generates MusicXML, it makes the definitions much more explicit and that makes it possible for Dorico to reconstruct the score.
You can bulk-convert Finale files using an option in Finale and that is your best option.
