Yep. The behavior Cor describes is exactly how the ChargePoint EVSE at work behaves. Each station has two J1772 outlets, but it is wired with a 40A 220V circuit. ChargePoint calls this charge sharing.
The ChargePoint EVSE can be configured to send you an email or a text when the charging power changes. You can also get notification when charging is finished or the charging connection is pulled out. You can also see your instantaneous draw and total charge for the session on their web site.
