Norton Family Premier- Internet Lock out

Is it possible to create a feature for next version of updates that locks out only the internet during the blocked time in Norton Family Premier with out locking entire device. Or does this already exist and I just haven't discovered it with in the app. Unfortunately this product seems geared only to a younger market and is really limiting itself by not having options for older users. I have a teen and don't need to restrict all usage just want to limit time spent online on social media to certain times of day and it appears the functionality doesn't currently exist within Norton's app.
