Add Quote Total value, dynamically calculated, to the quote main header

Summary:

Does anyone know how to add the total quote value into the main header and also being dynamic calculated based on the user actions on the quote (ex. change a price or quantity, delete or add another product)?

I saw this in one of Oracle CPQ product tour, also picture added below.

And I think would be better for users to have this information right in front of their eyes as this main header is sticky. But I did not manage to bring this to the layout by modifying the transaction layout.
