Phaser 3 different bounding box in atlas

[Pred05]

it is possible in Phaser 3 to define the bounding box for each sprite frame into an atlas ? When i generate an sprite sheet into TexturePacker, we can find some parameters into the .json :

Quote

"idle-0001.png":
    {
       "frame": {"x":1,"y":1,"w":423,"h":619},
       "rotated": false,
       "trimmed": false,
       "spriteSourceSize": {"x":1,"y":1,"w": 423,"h":619,
       "sourceSize": {"w":423,"h":619}
    }

and my sprite definition : 

Quote

this.sprite = scene.physics.add.sprite(x,y,'player-idle','idle-0001.png');
this.sprite.setCollideWorldBounds(true);

When i change spriteSourceSize or sourceSize, it doesn't change anything on my sprite is it normal ?

it is quite strange because the method setSize change well the bounding box. In the implementation of setSize the sourceSize is update so i think it is possible to set directly a bounding box with the atlas .json ?

     * @param {integer} [height] - The height of the Body in pixels. Cannot be zero. If not given, and the parent Game Object has a frame, it will use the frame height.
     * @param {boolean} [center=true] - Modify the Body's `offset`, placing the Body's center on its Game Object's center. Only works if the Game Object has the `getCenter` method.
