I know this is a bit of a niche thing for IX but as there is no other site to upload macro sets im limited in my options.

I have a macroset (https://item.mania.exchange/set/view/12304) that i expanded with more macros, but if i use the update button on the set page it doesn't update the set. It does however upload the macros as new items and they do link back to the set on their individual pages.
