How do you change the name of the ASP core 2 tempdata cookie name?

public class Startup
{

    public void ConfigureServices(IServiceCollection services)
    {
       services.AddSingleton<ITempDataProvider, Interfaces.CookieTempDataProvider>();
    }

}

public class CookieTempDataProvider : ITempDataProvider
{
    const string TempDataCookieKey = "MyCookieName";

    public IDictionary<string, object> LoadTempData(HttpContext context)
    {

    }

    public void SaveTempData(HttpContext context, IDictionary<string, object> values)
    {

    }

}
