Of course, initially, it is fine. But we may agree that is restrictive. On the other hand, I agree with you that we may have the problem of bothering the user with selecting the CoI (or at least an identity related with the CoI). In fact, I had something similar to Sam's approach but certainly involving the user may have drawbacks (though I don't see other solution so far). In any case, in my opinion, this is an interesting problem.

Best Regards.
