automatic sprite sheet animator

just like image sequence from image texture where it cycles through all frames uniformly infinitely, but this method depends n that frames are their own image, but what if all frames were on top of each other in a vertically long image (sprite sheet/image strip), there should be a simpler way (could be only me) to go through each frame cycle-ly without me having to add a texture mapping node, plugged to a texture coordinate (from uv), where the texture mapping's location input is plugged to a vector math node (set to multiply), and i have to keyframe the values each time, then make the animation into an animation strip and repeat it to fit animation
