Selection criteria by category.

Hello! What are the criteria for sorting assets by category? For example, by categories Props and Architectural visualization.

For example, my product (link) and another (link). A set of pianos and a set of sofas. By technical characteristics are very close. By appointment, the same - interior items. But, they are in different categories. It’s really important for me to know your criteria for sorting products by category. Or is it at the request of the seller, and there are no special criteria?

As far as I understand it, it is down to the sellers wishes. Though obviously Epic no doubt reserve right to overrule a decision if they disagree with the seller’s choice.
