Cars Island microservices, Can't add a second subscription

[nanderto]

Thanks I have found this immensely helpful, but one think I have not been able to do is add a second subscription to an event. It looks like this should be possible but is not. I may have misunderstood your intent.
This is how you register a handler with the IOC container.
services.AddTransient<IIntegrationEventHandler<CarPricePerDayChangedIntegrationEvent>, CarPricePerDayChangedIntegrationEventHandler>();
If I want a second handler of the event in the same microservice for example a CarPricePerDayChangedAuditEventHandler then I can do this the same way:
services.AddTransient<IIntegrationEventHandler<CarPricePerDayChangedAuditIntegrationEvent>, CarPricePerDayChangedAuditEventHandler>();
but when I go to set up the subscription I do not have the option of adding both handlers. the method looks like this.
eventBus.SubscribeAsync<CarPricePerDayChangedIntegrationEvent, IIntegrationEventHandler<CarPricePerDayChangedIntegrationEvent>>().GetAwaiter().GetResult();
It seems that what ever we specify last will likely get created by the IOC container.
