[JW Lua] Setting the auto-number style of a staff name

[Jan Angermüller]

Jari (or anyone else),

when adding a new staff via a JW Lua script, is it already possible
to enable the "Auto-Number Style" option for the staff name ?
(i.e. to automatically create "Trumpet 2", instead of "Trumpet" if one 
trumpet already exists).
I didn't find a function or any enums for that.

Thanks a lot for your hints !

Best regards,
Jan
