It is difficult to get an overview of how a variant is priced in different price lists. Now in the "Price" tab on a product, you get all variants for all price lists, you can't select or filter out a specific variant. If you have many markets and price lists it is therefore almost impossible to see the pricing of a variant on the different markets. This is needed to be able to assert that the pricing is consistent on all markets or to change the price for a variant across all markets.
Example: you want to change the price for a variant. You have 10 markets. Then you need to expand 10 pricelists, scroll to find the variant under each price list to change it.
