There is a visual style preferred by many composers and orchestrators in which instrument group names are shown bracketing two or more staves, with numbers (1., 2. or I., II.) rather than individual instrument names showing for the specific instrument staves:

This is a nice presentation, which clearly shows how the orchestration is organized with a minimum of clutter. The method to create Multi-Stave Groups like the above in Finale, as well as a cool variation for group name display are covered in this post by my colleague Jon Senge.
However, while this works great for the score, it’s quite another thing if you are also creating the parts, because there are no longer unique identifiers for each instrument. When you get to the parts phase, you first have to figure out which staff goes with which instrument, and once you do, you have to manually type in each instrument name in the Linked Parts! Ideally, the instrument names should remain in the template for parts. So, how can we do this?
