etcd clientv3获取请求的目的地

I was wondering if it is possible to determine to which server a put or get request is sent to?

Optimally this would be either:

_, _ := cli.Put(context.Background(), string(key), string(value))
server := cli.destination()

or:

_, _, server := cli.Put(context.Background(), string(key), string(value))

I'm expecting the answer to this to be to edit the source, but I'm hoping that there is a better option...
