Advanced Launcher alternative

Hey there,

just set up OSMC on my Raspberrypi 2. Works like a charm.
I have media on a remote server reachable via pptp vpn. Hence I installed the VPN client following the instructions at

They suggest using the addon Advanced Launcher to invoke linux scripts from within XBMC.
Now my question: Is there any way to invoke the command line script to establish the vpn connection from within OSMC.
I don’t want the VPN connection to be established on startup. That would be no alternative.

Best regard
