How to get Bodyslide data/preset from a body that didn't come with bodyslide files?

[psychophunk]

Hi,

 

I recently came back to playing skyrim and I currently have a UUNP bodyshape that I like. Problem is it did not come with it's own bodyslide preset.

 

Is there a way to "extract" the bodyslide preset from the .nif file so I can apply the preset shape to my other armors?
