Hi! maybe it's possible to fix / add features supported scenario below.
Actual we use token: old-price-new-price-difference-percentage
1. But... If we add discount on category and "new price" is again reduced 10-20%... token still show percentage only from price before discount. Without summary both reduction old / new price + discount by product / category
2. We add some discount by category, and again then this token not working / we can't add similar. Maybe it's possible to support this scenario?
