Staff label without numerals

I need to have a staff labels without numerals in the condensed score.
For intance “Flauti” without I and II. This is very common in traditional scores.
I absolutely need this for a large professional project.

Is there a way or a workaround to achieve this?
Thak you very much

There’s no good way to achieve this, Stefano, because you really need the flutes to still be numbered so that you can differentiate between them at their entries in the music. So they must still be numbered as flute 1 and flute 2 for that purpose, but if they are numbered in that way, you will find that the numbers will show in the margin. You may well have to resort to removing the numerals in a graphic editing program after exporting a PDF at the end of the production process.

Thank you for your answer.
I’m so sad.
