New group for custom settings

Hello everyone, everything good?
I would like to know if on this screen (image below) there is the option to create another group, for example a group for another page that is neither the home page nor the post page.
Furthermore, is there a maximum limit of custom settings that I can create? How many?

Hello @Peppe

Only the Site-wide, Homepage, and Post. Setting groups

The limit is 20. How to use custom settings in Ghost themes - Developer docs
