Rearranging Parts List

Hey there, I was working beautifying the individual parts to one of my scores when I decided to create a new part for my horn. This wouldn't affect how the score looks, but it would mean that I have two separate printable parts for my horns. I clicked "Parts" and then "Create new part" and named it "Horn in F 2". It appeared at the bottom of the "Parts" page, and not right under the first horn part. This means that when other users want to print out the 2nd horn part for my score, they won't find it at the top with the other brass instruments. Instead, they will have to scroll down to the bottom of the score and find it under the string instruments. What I would love is some way to move the part back up to the brass section.
