Nova: Custom panel title and custom text

Hi, I have two questions:

1. in resource view mode, with relationships fields, the "title" of the panel and the labels of buttons are the same per-resource. For example, if the resource is "User", the title panel is "User details" and the button is "Add user". There is a way to change this labels per-resource? In the same example, I would "User profile" for title panel and "Add member" for the button;

2)There is a way to add a custom static text above the title panel, specific per resource and actions (view, edit, add)?

Thanks!
