How can I configure Incoming Connections programmatically?

Given the proper user credentials in Windows 8.1, is it possible to programmatically create a New Incoming Connection, either via a Command Line utility or Windows PowerShell, in order to allow incoming connections VPN access using PPTP? I know I can do this via the GUI, but I'd like to do this programatically via a script of some sort. I'm aware of the port forwarding requirements / VPN passthrough of the firewall and/or router -- this isn't the issue.

I see there are a nice set of PowerShell VPN Client Cmdlets available for setting up a VPN Client, but I need something along the lines of VPN Server Cmdlets.

Any help would be appreciated,

Thanks,
