Unfortunally, there is no way of doing this out-of-the-box. You would need to code it in the controller to get the current context page and include this data into your view model. Please refer to the code from the HomeController of Dancing Goat example website:
var home = mHomeRepository.GetHomePage();
You can add some more properties into your view model and populate these from
home object. Basically, this is the way of doing things with Kentico 12 MVC approach.
