Yeah you will need to consider how that extra information is stored.
The Site Title and the post meta ( date, author, taxonomy terms ) are all built into WordPress and available in the Dynamic Data options.
The extra text will need to be saved somewhere – like the Manual Excerpt or a Custom Field. And can be displayed using GP Dynamic Content block or Post Meta dynamic data.
The list of posts, their either using a Taxonomy term that relates those posts or a custom field to store them.
Then to show the posts themselves they are using GenerateBlocks Pro.
Lots to think on. Let us know if you want any more info.
