Condensed staff label name

Hi all.

I am trying to achieve exactly what is being asked in the OP.
However, I am not finding any useful enough information. Changing the instrument name from “Oboe” to “2 Oboi” I understand, but how can I get rid of the numbering of the instruments?

Is it at all possible?

The house style I need shows “2 Oboi” on the first system, and only “Ob.” on subsequent ones. Who is playing is apparent from labeling in the actual music, so never any player numbers in the staff labels.
