Display child post content inside parent post instead of just outputting a link

After installing and setting up, I actually discovered this only appends links to child posts at the bottom of their parent post content. It seems there’s no way to actually output the content of the child posts inside the parent display page?

That’s what I was really hoping to do with this plugin but seems it’s not possible? So I guess the only way is to hack the plugin files to achieve this? Can you tell me if this feature is planned in the future?
