Consul - Route to all instances of a service if none are healthy

Is it possible to route traffic to all instances of a specific service if none are healthy?

An example is an AWS target group, it will perform health checks on allocated instances and route traffic to those that are healthy, but it will route traffic to all targets if all are unhealthy.

The AWS workflow works for our use cases and I would love to be able to do the same with Consul/Traefik.
