The "Overview" is a great little summary of all that we choose to display from that Student Register, and it would be great to show that overview when setting up the Module Integration in Configuration > Manage Registers. Unfortunately, the "Overview" is the only Section in a Student Register that you CANNOT integrate with other modules. But in some cases, this is the best Section that we would want to display to other users in other modules as it's a good summary, without having to give them access to all the other Sections of the Student Register with lots of data that is difficult to see the wood for the trees.
