Yes, only during the first import. It will appear in TradeGecko as 1st attribute (position). It is only possible during the initial import because Amazon can randomly change the ASIN value of a product, and TradeGecko has no way of registering this change. When this happens, we will not be able to sync.
💡 Alternatively, you can input the ID of the order that has been blocked and update the ASIN value of the variants.
