[solved]How to Make Folders Appear at Bottom of Menu

I see how to make "folders appear as files," which alphabetized folders and files together. Unchecking that makes the folders appear at the top of the menu. But I want them at the bottom of the menu. For other reasons, I need to have submenus pop up with mouse hover. That means that I often get undesired pop-ups of the folders at the top of a menu. So I want them at the bottom of the menu.
