Repeat block pages in module

Hi, I’m very newbie with this!

Modular pages

I want to do something like this:
My modular page:

    items: @self.modular
      by: default
      dir: asc
        - _hero
        - _highlights
        - _callout
        - _hero_2
        - _features
        - _hero_3  (maybe parallax image 3)
        - _text
        - _something_different

And wondering how can I do someething like this example of single page. Is it possible? How?

ALso. Im’m studying the one-page site skeleton, but always two or three Hero pages are placed at the start of the page, not as I want in the example above
