You can do this either in the wizard during the location configuration, or by navigating to Locations, clicking on the "..." menu, and selecting "Edit":

Now any time a user connects to VPN with Predefined Traffic option:
traffic to those networks will go through the VPN, and all other traffic will use the user's default router or internet connection.
