How do I make Hitboxes in a 2d fighting game using Unity with 2d ToolKit?

I am trying to develop a 2d Fighting Game. I bought 2d Toolkit prior to Unity implementing native 2d. So, I would like to know if the native 2d in Unity allows for the user to put specific colliders on certain frames to act as hitboxes and hurtboxes? If so, how is this done? I don't think I can do this with 2d Toolkit, someone please correct me if I am wrong about this.
