How do you make a CAS family "homeless"?

[Pyromaniac]

With awesomemod, the game occasionally spawns homeless sims to fill in certain necessary NPC roles (maid, mixologist, etc). Is it possible to create a family in CAS, then make them part of this homeless NPC group? I don't even want/need to assign them specific roles, I just want to be able to create a pool of homeless filth from which the game can select individuals for certain roles, rather than spawning new fugly pudding-faced ones.

Any help would be appreciated!
