That's what pause is for! Well one of the things. Personally, when I hear something kick off, or if I get a riot alert, I hop the game speed to pause straight away as it's only a couple of clicks and then I can have a nice slow look over the prison. I feel like that's part of the challenge of bigger maps, figuring out what and where needs your attention.
Thanks for the suggestion, it'll be added to my feedback list
