Site-Initializer: parent and child page

Issue

• We are looking into how to generate child pages with the site-initializer. Can we use the native Liferay to generate child pages or do we have to go through code? Besides, maybe there is a simple way to override the native code?
  

Environment

• DXP 7.4

Resolution

• Child pages just need to be added inside their parent page's folder doing the following:
  

  layouts
  |----->1_home
         |----->1_subhome
         |        |----->page.json
         |        |----->page-definition.json
         |----->page.json
         |----->page-definition.json
