Pass in a list of unicast_peer ips?

Just wondering is it possible to pass in a list of IPs like this

```
$ docker run -d -e UNICAST_PEER="192.168.64.5 192.168.64.6 192.168.64.7" alterway/keepalived:1.2
```

and have them filled as following?

```
unicast_peer {
    192.168.64.5
    192.168.64.6
    192.168.64.7
}
```
