since prisoners follow the usual 'sleeping at night' schedule, it can become rather awkward for the wardens to chat with them, the window of time during which they're all awake for interaction becomes much smaller
once in a while, my wardens walk over to chat with them just for the prisoners to go to sleep before they arrive
so being able to set schedule for prisoners - at least the sleeping time - would be nice (or whatever the solution might be 🤷♂️)
