TOC, LOF, LOT question

Hello! I have a huge book file we needed to add some chapters to at the last minute. As such, I had to create new paragraph tags/elements for the new chapters and now I need them to appear in my TOC, LOF, LOT, and LEP. The problem is when I update my book it doesn't ask me if I want to add any other elements anymore - is there a way to add elements so they appear in your auto-generated files? I'm specifically having problems with my LEP. It just updates it. I need to add more paragraph tags!
