No, there isn't a way to do that with augtool. I'd be more than happy to
take a patch for that, e.g. to have a new command 'setm path v1 v2 ...'
- it could be done entirely within augtool.

As an alternative, you can do it in your favorite scripting language,
e.g. in Ruby, this would be something like

        def setm(aug, path, values)
          values.each { |v| aug.set(path, v) }
        end
        
        setm(aug, "/files/etc/group/mygroup/users[last()+1]", ["user1", "user2", "user3"])
        
and might be a nice addition to the Ruby bindings anyway ;)
