How to change the order of divisi staves?

I am currently trying to make divisi parts but when I created solo, the new staff (solo) is below the section player staff, how to move my solo staff above the section player?

You can’t move the solo staff, you can only start a divisi with an extra staff below, turning the upper staff into the solo staff. This has been discussed before, and the request to change this restriction is certainly known by the developers.
