Can you delete maxis created bin sims?

[Tyrion101]

Under Nraas SP or MC (I can't remember which ) found  the thing I've been searching for a way to import sims and sims based on sims I've created, it isn't perfect but it's good enough. Essentially it moves sims in based on, or exactly like those in your sim bin. So is there a trick to deleting the maxis created sims?
