Ok, that works somewhat, but then I have to take the tabs out. What would be nice is,
Step 1. Press “Ctrl + A” (Select all, or select the lines desired)
Step 5. Press “Alt + N” (Numbering…)
Step 6. First Line = 001 , Increment = 1, Insert in column: 0
Step 7. “OK”

Step 6 is a new choice in the numbering function that would allow entry of numbers or sequential characters in the column chosen. Column 0 is before column 1.
