Ability to move ebay sales from one variant to another

Many one piece cards have ebay sales from a variant listed against them. This often over inflates the price estimate for the base rarity of that card. I appreciate that it would be difficult for an automated process to identify specific variants of a card, especially when there is often no official ID for those variants. 

My understanding is that contributors only have the ability to report an incorrect ebay listing, I was thinking it would be efficient for users to be able to also be able to shift the listing to a variant of the card it is currently listed against.
