setRepeatDelay on Group Animation

[Roosey]

I have a group, jewels, that I am animating all of the children of using jewels.playAnimation(). I was wondering if there is a way to add a setrepeatDelay() on to all animations within the group. I've had a look through the documentation but it seems to be fairly limited on group animations. I know I can do this by iterating through the group but I was just wondering if there's a way of doing it without needing to :-)

Thanks for any info!

var jewels;

function create() {
    jewels = this.physics.add.staticGroup();

    /***** 
        Create sprites code in here 
    *****/

    this.anims.create({
        key: 'jewelAnims',
        frames: this.anims.generateFrameNumbers('jewel', {start: 0, end: 6}),
        frameRate: 10,
        repeat: -1
    });
}

function update() {
    jewels.playAnimation("jewelAnims", true); //.setRepeatDelay(2000)?
}
