Leveling and Star gains - an additional option to NOT gain star rating

Been trying out the mod and the leveling for tames is pretty cool, but one thing I would like to be able to control is whether or not a specific tame gains a star rating that would change its appearance or not. For example, if I want to level a moose, I don't necessarily want it to gain stars and go from having no antlers to the one with antlers, as I'd like to keep a mix of both. But, other tames I might want their appearance to change, etc. Thanks for the mod!
