Is it possible to add a load balancer rule after the load balancer has already been created? For example, if there was no backend when the load balancer was initially created, and a new backend pool is added later using

LoadBalancerBackendAddressPool

, can a new load balancer rule be created? When the load balancer resource was created, the backend didn’t exist, so it wasn’t possible to create a rule with that backend. What is the point of having a separate resource for the backend address pool if a new rule cannot be created?
