Using Multiple Models in single class in ASP.Net MVC

Hi

Can i create all ViewModel in 1 class instead of creating separate classes.

public class LocationVM
{
    public List<Location> Locations { get; set; }
    public Location Location { get; set; }
}

Other i want for Customer
public List<Customer> Customers { get; set; }
public Customer Customer { get; set; }

Thanks
