Offset a gani's x,y position in player.attr[]

[Cubical]

I currently have a few animations that use particle effects that I would like to use without having to make new ones just to offset it by 0.5. I've never been in a situation where I feel like it's be more practical to somehow modify the x/y instead of just creating a new gani. Is there any way to access and modify the properties of a gani stored in a players attributes or will i need to just create new ones? I don't mind spending the two minutes fixing each one but if I can just manipulate it I'd rather do that.
