Currently, MP postings are for a single version of a product. When a creator has, for instance, color variations of the same product, this results in the same item appearing numerous times in the search results. This is tedious for the user to have to wade through an item that they have already decided they are not interested in sprinkled through out the search results. Similarly, demo versions also duplicate on the search results.
I propose that the creators are given the ability to create child products. Only the parent version would show up in search, but once the user has clicked on the product listing, it would then show the different color variations and have a separate button to get the demo version if one exists.
After this feature is implemented, a suitable time should be given to creators to clean up their listings before implementing a rule on "no duplicate postings based on color/style variations".
