Adding "world edition" nintendo games

It would be nice to have separate listings for "world edition" Nintendo games, which are essentially ESRB versions of some Switch, 3DS, Wii and Wii U games specifically sold on middle-eastern and southeast asian markets. The game inside these versions is exactly the same as the NA counterparts, but due to the differences in the covers (which range from a small circle saying it's the world edition to a different cover art entirely in some rare occasions), the prices of these copies thend to be different from the actual north american games, especially for sealed copies (e.g. Mario & Luigi Paper Jam, sealed world edition copies are easily found for ~$40, meanwhile actual NA copies go for upwards of $100). 

I'm not sure if it's feasible since these games usually have the same UPC and many ebay listings don't mention that they're the world edition version in the title (sometimes it says "middle east version" or something like that), but it would be a nice feature to have.
