Hi Mevrick,
There are two ways to do it.
1. In the overview Page use methods DETACH_STATIC_OVW_VIEWS, REATTACH_STATIC_OVW_VIEWS to dynamically hide and unhide the Views.
2. Maintain different Ui Configuration and as per your business logic call the desired config in DO_CONFIG_DETERMINATION method.
Have a look here.
