Auto grid cut Sprite in edit source region?

I am a complete beginner in unreal (know a little about unity3d)

So basically when i watch the unreal “2D Sidescroller with Blueprints (4-create flip book)” on it’s website i see the guy have to cut multiple sprite (that can’t be auto-cut using extract sprite) by manually make sprite from texture then duplicate it 16 times and batch adjust the width-height x-y of the sprite manually. My question is considering we know the size of each sprite (in tutorial 250x250) is there a way to just automatically cut the sprite-sheet by entering the sprite size?

In Unity3d there is a feature automatic slice → grid which basically cut sprite in grid using the sprite size and start x,y is there equivalent feature in unreal?

If there is already question like this posted before please give me the link.
