We are sorry to say you that we don’t have any shortcode for page layout. But blog layout on customizer may help you on this.
You can use masonory blog layout. directly from customizer. For this
Go to dashboard -> appearance -> customize -> Basic setting -> on blog layout you can find Masonry with no Sidebars checkbox -> after checking on this you will get 4 column layout.
Let us know if we are understanding fully or perhaps this not what you meant for.
