Changing hitbox with each animation frame

[NumberOneRobot]

I am trying to make a game using Phaser that will have some fighting aspects to it. The problem I'm having is how to assign each frame a different set of hitboxes. I understand how I can create different hitboxes for a single frame of the animation, but how I cycle through a set of hitboxes as an animation is happening is where I run into trouble. From looking through the source code and all the examples, I couldn't find any aspect of Phaser that will support what I want, and before I get in too deep with Phaser I want to make sure this is possible.

 

Thanks!
