Have a group with children not collide with itself?

For example, take this:

bullets = game.add.group();			bullets.enableBody = true;			bullets.physicsBodyType = Phaser.Physics.P2JS;			bullets.createMultiple(125, 'bullet');

So, 125 sprites will be generated. Now, these 125 sprites will collide with themselves in the world.

 

I am curious if it's possible to set them to not collide with themselves only, but still be able to collide with other objects in the world?

Looks like changing the motion state will make them not collide with each other. And that's what I ultimately want with the ability to collide with others, so I found this:

bullets.setAll('body.motionState', 3);

So I guess this works for now.
