There's no way to do it automatically, if that's what you're asking. You have to link every single word form to the parent word manually. It's tedious but it does force you to slow down and take your time with the text.

I don't personally use LUTE because I prefer Language Reactor's reader because it lets you do instant lookups without having to add your own definition. I don't care about saving words so I only use the free version, but the premium version claims that it marks all related words.
