I always, always, ALWAYS rename my liberals so that their first name they get is usually more of a squad designation (for instance Writer) , and the second has a simple designator of number (alpha/beta/cappa/delta) and if the character has a special skill I include that too. So I'll have CovertOpsAlhpa(Lockpick4).
They also organize by safehouse.
When my numbers get big, I'll make sure active squads get an A at the start of their tarting with A, and stuff that never has to move (writers, artists) get a Z.
Generally my squads work like this.
AlphaHacking Squad goes between the two downtown appartments, since they draw heat like mad as they run credit card scams.
BetaAction Squad (Legbreakers and the assholes wtih guns who take out the CSS..and then getting killed in a blaze of glory)
BetaHuman Resources Squad (which has my leader who kidnaps sleepers and brainwashes them, running between various other safe houses)
OmegaWriters and WriterGuards (who sit in a fortified safehouse and write the guardian once the laws become reasonable.. and I NEVER put out treasonous material from this location)
ZetaDoomed/Prostitute/Graffiti Squads (who sit in the homeless shelter. Doomed refers to known kidnapped and brainwashed conservaties, and the useless idiots I pick up who run graffiti and prostitution stings, largely to train my lawyer). These guys are pretty doomed and usually they all end up in prison a lot unless I've gotten their Street Sense way up.
For my sleepers, I usually use the location they are at.
The exception being my six sleeper judges and my ace attorney, Phoenix Left, who of course NEVER do anything but act as sleepers, as they are too valuable to risk.
