Shared device amongst children

Is it possible to configure it so that one device is shared amongst the children in our family. We have a laptop which has 3 accounts on it for our 3 children and I want to be able to monitor the usage of all the children. However, when I add the device and the accounts to the system, the computer is moved across the children so only one child is monitored.

Is this correct and when is this going to change as it is a bit of a weakness. Bitdefender looks a great product but this is surely a bit of a lack of understanding of home IT usage.
