Adapt 24 fps footage to 30 fps

This is opposite of what most people would want to do, but I would like to add a piece of 24 fps footage to a 30 fps comp so that 24 frames still takes 24 frames, meaning the footage will play back a little faster and run a little shorter. In other words, at 24 fps, 120 frames takes 5 seconds to play, but I would like to drop it into a 30 fps comp so that it takes 4 seconds. I know I can time remap it, but it would be neater and more precise if I could just tell it to align the frames as they are. Thanks!
