i don't even know if tis is posible, but i'll ask anyways.

I'm working on a hat, and i want to ad jiglebones to make it look better. the question is:
Can i configure a jigglebone to be always facing up?
The hat is a balloon, and when the player crouches, the whole hat leans with the player, but i want it to be facing up (like a balloon filled with helium would be).

As i said, i don't know if this is possible, but if it is, how can i do that? Because i have no idea, as is the first time i use jigglebones.
