Add the following to “Submissions”, after the other content but before any of the subrules

If a Submission requires a Broker to refer to the title of a piece of art, any title which clearly and unambiguously indicates which piece of art the Broker is referring to may be used (although Brokers are encouraged to use the full title). If the title they use does not clearly or unambiguously indicate a single piece of art (out of the pieces of art that are valid to be targeted in the submission), the submission is not valid and the collector should inform the Broker of this fact at their earliest convince.
