Hey Nicolo,
I get where you're coming from. Sometimes you have just a little bit of dynamic info you want to display on a page. Unfortunately in this context, it is required to display that dynamic info using an object, especially since it's dynamic.
With that said, you can implement the use of a nanoflow as your default "Home Page" and perform the logic necessary in the nanoflow to fetch your relevant information and route the user to the home page, now with the necessary context to display your message.
I hope that helps!
