Networker V9 Notification

Sorry for my bad english... On Networker V8 it was possible to set a notification command with

"/bin/mail -s "hotnetworkerb.fbn-dummerstorf.de's savegroup '${NSR group}' failure" root"

On V9 this ${NSR group} does not work. There are no hints in any guides. Which variables are possible in V9?
