bot framework composer creating machine learning entity

I'm building a chatbot, but I don't know how to add a complex machine learning entity, what I'm trying to do is to request fullname and extract first name, second name, middle name, etc. I know how to do it by using LUIS interface bot with bot composer I feel a little confused.

Something like this, but with bot framework composer:

Language Understanding (LU) is a core component of Composer, allowing developers and conversation designers to train language understanding directly in the context of editing a dialog.

As dialogs are edited in Composer developers can continuously add to their bots' natural language capabilities through a simple markdown-like format that makes it easy to define new intents and provide sample utterances.

Here is the sample for Built-in Language Generation and expression library.
