How to manage stacks (services (containers)) on a re-added host?

I created some stacks on a host, I removed the host then.

I added the host a while later, I hope containers on the host can be discovered by rancher again. But I found rancher can not manage the existing containers, rancher will re-create all containers.

How to let rancher re-discover the containers on the re-added host, not re-create containers ?
