Is there any way to track my kids weight on the Garmin S2 scale?

I want to be able to track my children's biometrics as they age and it will be fun for them as well to see their biometrics as they grow up, but I'm not able to add them to the scale unless I create a profile and lie about their age in the profile creation menu, as the menu only accepts 26 year olds and older. But then I thought that there might be some family option or some workaround that should exist, anyone know it here?
