Bandwidth Usage Alert

Is it possible to get some kind of notification if I reach a set limit of bandwidth usage? Like I have to be notified if I use 50% of the 160GB free-tier bandwidth. Is that possible?

I did get a bandwidth alert (email) a couple of days back, so I believe there are alerts in place to warn you of potential misuse / attack. I don’t think there are alerts for exceeding free-tier usage.
