Is there some way to see an item's rarity before its rarity changed? I thought subetalodge would be a good source for this information, but it only shows the current rarity.

If an item used to restock in a shop but was later retired or the rarity changed, is there a way to see its rarity before it was retired?

I had a bunch of items in my pet's treasure from years ago, but I didn't take a screenshot when I removed the items. Now I want to add them to a category in my gallery. My memory may have to suffice.
