How to stop frames from autofilling gaps on the timeline

So I’m doing frame by frame animation and every time I go to draw an in-between frame that isn’t next to the previous frame, it auto fills up to the frame I’m drawing. It’s really annoying having to go back and reset the exposure. Is there any way to keep this from happening?
