I found the link, but I wouldn't recommend it except to people who don't have a computer because it's so easy to make your own customized Notepad. I don't know why I didn't think of it earlier.

Simply open your computer's Notepad application.

Type in:
A
B
C
(etc.)

or something like:
Memos
E-mail
Book Ideas
Misc.
(etc.)

Save and import your Notepad file into your Kindle, then open it in your Kindle.

Bring your cursor to the desired location. Type your note and save. To view, edit, or delete your note, click on the superscript number that has appeared beside that entry.

To view all your notes, open your file and select "My Notes and Marks."

To view on your computer, import your Kindle's "My Clippings" file to your Documents folder and go to the last entry for your desired Notepad section.

Cripes I feel dumb. It was there all along.
