Lo-Fi Games

I wish to create specific unique npcs that are predesigned.
The method I'm using to do this, is to design the character ingame, save the .body, and use that .body in a mod. The only question I have, is there a way to preserve that .body file within the mod, rather than the mod having to reference the file?

Case being, i'd rather not have to include that .body with my mod. Or is that the only way?

As far as I know, the only way is to include that body file with mod. It shouldn't be that much of a problem if you set up the folders correctly so they automatically go to the correct location when your mod is unzipped.
