Nope. Paizo added the codes without ever consulting us. We learned about the codes at GenCon last year, when players came to our booth and asked us about it. Apparently, Paizo had some plan for them, but they've never adequately explained that plan to us, so we're still not sure what they expected us to do with those codes. And since it was something we never had any input on, I'm not even sure we could cleanly implement whatever they had in mind (assuming it was someday fully explained to us).
Sorry I don't have any better news on the subject...
