Ok, I see.
Anyhow, one approach could be to use the output from command ls below cd ~ ls -d */ which lists ALL not hidden user top folders.
Another approach is to extract the default top folders from the file ~/.config/user-dirs.dirs and adding the home folder.
From that those top folders can be removed from the "bookmark list" in the quicklist.
The second approach is more in line with Nautilus computer folder list content.
