accidentals only before the notes

I have a transposed score for bas clarinet and piano. I would like to have the accidentals of the bas clarinet before the notes, not at the beginning of the staffs. What I have to do? I cannot find it in the manual!

I think you’re looking for the atonal key signature. Simply type “atonal” in the popover as you would “c” or other applicable command.

Thank you very much!
