I'm not sure if I've ever heard how this is handled exactly. I know we had some lengthy discussions on this very subject early in the 950's life (since it had a similar triple crossover). If you haven't done so already, dropping a line to Outlaw (either electronic or on the phone) might be enlightening - while they monitor the saloon, they tend to stay pretty quiet so as to let us carry out our discussions and debates on our own. Others may also know the answer this, and if you do talk to Outlaw we'd all like to hear what you find out.
