When you import sections from another Finale document an it's not using the exact same standard articulations, expressions, chord symbols, etc. these are appended to your existing document. Next, when you'd like to replace those with the correct font you are using in your new document, you can delete the articulations and expressions from the list. When doing so, Finale lets you replace the old ones (the one you are deleting) with the new ones.
For example, you delete the appended "Maestro" staccato dot from the list and replace it with one you made yourself in the new document which should be higher up in that very same list: All staccatos in the document now use the new dot. So far so good.
However it gets irritating when you import many sections, maybe even from different source documents. Your lists of articulations and expressions become longer and longer and you need to delete and replace those entries manually. On a bad day, I would do this alone for an hour before the imported sections of a large document all look the same. Hence the following feature request:
#1 Articulation and Expression import tables
When Finale discovers that an imported (copy & pasted) section from a different document contains anothing new that has a LIST (articulations, expressions, chord symbols, etc.) it should open a window where you can map the imported ones to the new ones - all of them in ONE GO. When you then hit return, the entire document looks the same.
#2 Staff styles
Unfortunately with staff styles, this is not possible at all. At the moment you can't even replace a staff style with another when deleting it from the score. However new styles are added to the list nonetheless. Sometimes I have up to 4 different "slash notation" styles in my list, just because I imported sections form another document - even if they are exactly the same. This is messy and should be stopped, just like above.
