Debugging (Feature request?) - Step through game frame-by-frame (for inspection)

Hi, I watched a video the other day about ’ Nier: Automata ’ and in that game there is a debug mode which allows the developers to step through the game frame-by-frame. Meaning that the game is ‘paused’ and every time you press a particular button, the game proceeds by a single frame. I think this is very useful for inspecting cinematics and other types of transitions/animations. Does this feature exist in UE4 already?

I think this is very doable by creating an actor with a tick function and some other dummy function you set a Brakepoint at. And then you get a break once every Frame.
