You can use Pin at start of layout or on creation, but you first have to manually set the position and angle to match the player object (Pin is relative to its starting position). The alternative is to update the position of the player character to match that of the player box every tick.
Just FYI, what you want is for the user to control the boxes, not the animated character, then update the character to stay with the boxes. All controls should be assigned to the box for the most accurate collisions and controls, and animation changes should be assigned to the character.
