How can one exclude special items in a folder from being shown?

How can one exclude special items in a folder in the Binder from being shown when selecting the folder containing that item. E.g., 10 documents in a folder, the content of 4 of them shall not be displayed in the editor when the folder is marked.

You can’t exclude files from scrivenings mode without ctrl-clicking on individual files. If these other files are notes, you could move their contents into the document notes of other files, or even into the text of the folder itself (you can toggle whether you see a folder’s text in the scrivenings mode or not).

Thank you very much.

Alright, I understand.

Where could I do it?
