How to order parts?

Hey there, I wrote a piece in MuseScore Studio 4.4.4 with a lot of parts. To prepare for publishing on musescore.com, I started formatting the individual parts. I had one horn with 2 staves, so I created a new part for the 2nd stave. (Note that this didn't change the original score) So now in the "Parts" section I have "Horn in F 1" and "Horn in F 2".

The problem is that the new part has been automatically placed at the bottom of the "Parts" list. The 1st part is at the top, and the 2nd at the bottom. So, is there a way that I can move the 2nd part up, so it's right below the 1st part?

(This isn't so much of a problem for me, but if someone else is viewing the parts, they may get confused as to where the 2nd Horn part is.)

Thanks in advance!
