Folder naming structure

After the update from Kirby 2 to 3 Kirby created duplicate postings. Where do I define the folder naming structure for the content folder?

The folder numbering is set via the num option in your blueprints. The numbering scheme is set in the blueprint of the subpage, not the parent (this is different from Kirby 2). See the Starterkitsnote.yml` blueprint for an example.

title: Note
num: date
icon: 📖

Thank you!
