Currently, the only way to add a Route to a load balancer is to update the entire config of the load balancer and append the route's JSON into the appropriate place. Can there be a separate API call that will take care of attaching routes to load balancers instead of having to maintain the entire load balancer config and make changes to it? This would make managing load balancers that have multiple routes much simpler, as we no longer have to make changes to a load balancer, and just focus on adding or attaching a route.
