Place graphics with the ability to not only link/unlink graphic attributes between score and parts— which Finale already has— but globally set graphic attributes for ALL parts (independent of the score's graphic placement), so you don't have to adjust the graphic attributes *one-by-one* in each linked part.
When you place a graphic in a score, say, the cover page, its graphic attributes (placement, etc.) by default flow to all parts. If the page format of the score and parts is the *same*, this is no problem.
If they are *different*, however, which is often the case for scores with a lot of instruments (longer page for the score; 'standard' size for parts), the graphic placement in linked parts can get wonky. Although you can unlink the graphic attributes between score and parts, Finale doesn't seem to have a way to globally adjust graphic attributes in just the parts (while leaving the score's graphic placement alone).
