Auto-connect VPN in Kali Linux?

I currently have a working VPN on my Kali Linux box however I feel uncomfortable with the fact that sometimes I forget to manually connect it in the network manager. After digging around everywhere in the gnome-control-center network I can't seem to find anyway to initiate the VPN connection automatically. Is there something I am missing or perhaps an alternative for a network manager GUI? If not, how could I add the terminal commands to execute during the boot process?
