When I transpose a certain section of a score using the Transpose Tool (usually in keyless situations or where no key change should appear) chord symbols are not being transposed along with the rest of the area.
I always have to go to Change->Chords->Transpose->OK (4 actions!) to have the chords line up with the rest of the score again.
I can't think of a common situation where all notes of a section are transposed but the chords remain the same - musically, this makes no sense at all.
If, however, you need the chords to stay the same although everything else will be transposed (will be interesting how that sounds) one could go the above way using the Change->Chords->Transpose->OK to transpose just the chords back to their original pitch. I doubt anyone will ever use this, though.
Please implement that. It has been a very questionable behaviour of Finale that I have to explain to my students over and over again. It makes no sense and is one of many unneccessary timekillers.
