NQuery or Query with overlapping planning regulations

[Carlo A. Bertelli (Charta s.r.l.)]

Thank you, yes I think the overlapping regulations would always be
less than 10, perfectly feasible as a solution, but how to decide when
to show a target page - because we have only one option - or a
selection page - because we have two or more answers?
