Question about EA Hair Meshes

Hi. It’s a matter of what the package contains.
Example 1:
- you reshape a snowy escape hair and replace the original meshes in the package;
- the textures stay unedited and referenced, not included in the package.
- people need snowy escape to use this hair because of those referenced texture.

Example 2:
- you replace the bangs of a BG hair with that of snowy escape one;
- you change the meshes and the textures;
- now this file requires no snowy escape at all because all resources it needs are included.

You can add a pack requirement to this file. However, the last time I checked, the files still showed up.
