I have some math that may help. You can set X Y through this equation. All you need is and angle and a distance. The rest is trigonometry.
left arrow is pressed
targetY = Sprite.X + d * cos(180)
targetX = Sprite.Y + d * sin(180)
down arrow is pressed
targetY = Sprite.X + d * cos(90)
targetX = Sprite.Y + d * sin(90)
as you can see you are only changing the angle. If I were you I would save this. This will allow you to pick a point, from any sprite, move a sprite to it, or move that sprite to it.. Move ant sprite, any distance, in any direction.
Swap d out for distance.
