Clone models

Before i go into details, i'm looking for help and if this the wrong section, mods please move the topic
Now let's get back on track..... In the pre-Steam version in order to clone a car you just revise it and save it with a different name. Another option was to copy/paste the car file. Now what i want to do is to copy the whole FAMILY (even if there are no trims in it) so i can apply facelift and/or create a sportier model (fixtures wise). I tried copying the family and trim files and renaming them, but they wouldn't show in the game.
So how do i clone the car family
