In the VBAI Dev environment, we currently have the ability to enable/disable overlays using the "setup overlay" button. This request is to provide access to access the overlay enables programmatically. The use case is for when operators are required to show/hide specific overlays. When many overlays are involved, the overhead for programming these using the state diagrams becomes overwhelming. Below is an example for only 6 overlays. You can see how 30+ overlay groups would be a nightmare. There is also a overhead performance hit.
