Flagging content as internal/external at upload?

I understood from the Project Forum that it would be possible to mark content as relevant for SAP-internal or external audiences. However, I've just uploaded some documents, and couldn't find this option anywhere.

I also thought it was mentioned at the Project Forum that it would be possible to write an abstract for a document when uploading, so that others could see what it was about before opening the whole .pdf file - I couldn't find a field for that either.

Am I missing something obvious, or are these functions not available (yet)?

Thanks and regards,

Sarah
