Support for saved state handle

Can we have something like parameters passed to the screen are automatically available in the viewmodel saved state handle, helps in initial load of the data,

also regarding the navigator scoped viewmodel it is available in 1.1.0-beta01 but can't find it in the 1.1.0-beta03. Also can we get koin integration for the navigator scoped viewmodel can see it for screenmodel but not for viewmodel
