Setting permissions for which networks an app can access

Is there a way to restrict which networks an app can use? For example, I don't want to use a location-based dating app (or similar, e.g. Snapchat) on my work/university/school network. I would prefer those apps to only access the internet from my home network (private) or cellular data (again private). This is to avoid legal issues, etc. I've set network settings to "restrict background usage" and also restricted networks. But as far as I can tell, this only stops apps from accessing the internet in the background. I'm using Android Lollipop on a Samsung in case that makes a difference. How should I go about restricting the particular networks (WiFi, cellular) that an app can access? Is there an app I need? Do I need to root?
