I just noticed that some of my shirts have minor glitches in their art. They're not obvious but I want things to be perfect. Other times, I've spotted mistakes that need to be corrected, or just had an idea for improving a design. Right now, my only option is to delete the shirt from Merch and upload new. Which is ...okay. But what about BSR, ads, links on blogs etc. that point to the old design? It would benefit everyone involved if those still worked and people simply got the corrected or improved art.
Obviously, the whole thing would need to go through review again, and changes that are more significant than just fixing a minor mistake should get a new listing, but ... I'd like this option.
