Is there a way to highlight more than one instrument in the ScoreManager?  Not often, but sometimes I have to move a section next to another section on the score, so I can see how the chords stack up, e.g.

Today, I have to move all the percussion below the strings (orchestral score), and would like to be able to do it in one fell swoop.  Alas...

Perhaps there's a feature I'm not aware of?

Also (I'll have to make this another post, probably), though I print and sell sheet music, my main focus is on creating orchestral soundscapes, and Finale is great for it!  But it takes a lot of research, trial and error, etc.  With all the technology Finale has invested in making world-class manuscript, there don't seem to be many videos, etc., on engineering sounds.

This would be beyond the volume/pan settings, and the settings available in the Aria Player.  It's already so good that I can't tell the difference between a string quartet on YouTube and my Finale file, sometimes, so it's not a crisis.

Again, maybe there are resources I haven't seen yet.

Thanks!
