Show flow number to left of first system?

Scroll down to the bottom of that thread I linked to above until you get to:

Flow title position

If you add an empty section player (by pressing Shift-Alt-P in Setup mode but not selecting an instrument in the picker, just press Esc) you can just drag the piano instrument from its original solo player to the empty section player.

Unless you need to add extra staves at any point, it shouldn’t really matter whether the piano is held by a section or solo player.
