Add a new sub-rule to “Private Collections” called “Sets”

At any time, a Broker may combine three different Pieces of Art in their Private Collection into a Set, which is defined later in this rule. A Set is shown in a Broker’s Private Collection using the following format: {‘Piece of Art #1’ [Price], ‘Piece of Art #2’ [Price], ‘Piece of Art #3’ [Price]}, where each instance of ‘Piece of Art #n’ is replaced with the corresponding name of a Piece of Art, and each instance of Price is the corresponding price to the Piece of Art listed directly before it. When Pieces of Art are combined into a set, the individual Pieces of Art are removed from their Owner’s collection before the Set is added to the Owner’s private collection. If doing so is impossible, the Owner of the Pieces of Art may not combine them into a Set.

At any time, a Broker who has a Set in their Private Collection may choose to separate that set. If they choose to do so, the Set is removed from the Owner’s Collection and the Pieces of Art that were in that Set are returned to being shown separately.

A Set is defined as one of the following:
* 3 Pieces of Art that were all posted as part of the same round
* 3 Pieces of Art that were all submitted to be part of a round by the same Broker or Idle Broker

The Owner of a Set or Piece of Art is the Broker or Idle Broker for whom that Set or Piece of Art is in the Private Collection of.
