How to file favourites help please

[Big-G]

I currently have 4 folders on my 660-
All favourites-Address book-Category 1 (dealer download from this site) and Vehicle services.
I would like to create more folders so I can split some of my favourites up for ease of access and to stop duplication like all dealers in cat 1 repeated in All favourites.
Is it possible and if so help please.
Cheers
G
