How can I make a subfolder that looks and behaves like Documents/Music/etc?

Question

The home folder starts with default folders (mostly XDG base directories) like ~/Documents and ~/Music. These are decorated as follows:

1. custom folder icon (not an emblem)
2. custom icon matches the style of the regular folder icon
3. Nautilus bookmark in a distinct section (separate from other bookmarks)
4. custom bookmark icon

I have created a non-XDG folder called ~/Work. How can I decorate it with all four features listed above?
