Need a "Snap Shot" Historical View in CAD for Case Reviews

In our old CAD, we had the ability to see an historical screenshot of what the CAD looked like at the time any request was assigned. It made it much easier to perform case reviews as we could easily see the status of each asset at the time, pending versus active trips, etc. It would be great to have this functionality in Dispatch Pro. This request is more for the admin side but would make it much easier to put together reviews for Risk, the Ops team, and Exec Leadership.
