Add another Detail when editing song

I would like a detail entitled Arranger. Is it possible to add detail types? Thanks, Ann

Unfortunately you cannot add additional details fields.
There is an Authors field.
Could you do it using Categories? You just create a new category with the name of the Arranger and assign that Category to the piece.
Another alternative would be to use the Archive number field. This can contain text and numbers.
All these would be searchable in the Quick find.
