Character Name Change After Introductions

[heirofmaul]

Ok, here's a tricky-ish but important one.  Is it possible to change a non-player character's name during the game so that it appears different after speaking with them.  For example, say there is a character labeled simply "man", you talk to him and learn his name is Bob, so the next time you run the cursor over him, it now says "Bob".  Can this be done and could someone please explain how?  Thanks.

Not tricky at all, in fact it's in the BFAQ.
