It's not something that's "only gotten," I think, and should definitely be respected as such. I don't mean to sound aggressive in any way, but I do mean to be direct. JS and CASS isn't something I'd take lightly. It's cockpit access, on an aircraft which very well contain two hundred and fifty thousand pounds of "stuff," heading across the world in half of a day's time.
That all considered,
I do believe it is still sign-off, have-fun-be-safe at CKS. If it isn't right after the init training's completed, it's probably already been the 30 days' waiting time from hotel check-in, to once your initial is done.
As stated above, there's probably plenty of CKS folks who could or would be able to help.
