@BR: no special tweaks/anything are necessary. Calibre uses the author string, whatever it is and how it is, as the folder name. If your authors are "LN, FN" then the folder names will be "LN, FN". If the authors are "FN LN" then the folders will be named that way. If they are mixed then the folder names will be mixed.
The following is a small snapshot of the author level of my library.
