auto capitalize section title on compile?

When I’m in Compile > Section Layouts > Title Options I see “Title Case” options as
Small Caps
lower case

Question 1: Why no Capitalize each word (expressed in appropriate lingo) or Sentence Case option?
Question 2: Is there a code I place here (or elsewhere) or some other maneuver I can use so the capitalization of each word in the title happens regardless of how I typed them in the binder—all lower case or whatever?
