Either you buy the tabs at an office supply shop or prepare to do some cutting.
Some manuals use color coding squares printed physically on the right edge of
pages so when you looked at the side of the book you could easily find all those
items in the red, blue or whatever color. This would take a printer that could
print to the edge.
Perhaps you could print the divider pages in a new publication, rather than
using letter paper, use card stock, setup your page the same height as your
booklet, but a little wider to accommodate the tab. You could even print your
items on the tab. You still would have to cut.
