I'm currently using Oberlo which shows the price I sold it for and the cost of the item, however the cost of the item is based on the standard shipping that I used when I input the product in Oberlo. I typically ship with epacket with a slightly higher cost.
Is there an app that automatically imports the cost of the product based on the actual Aliexpress transaction? Instead of the cost of the item that was originally imported from Oberlo?

I'm not aware of any apps that show profit margins on existing orders for which you can modify shipping costs.
Only app I know of in which you can adjusted shipping costs and see profits is this app. It calculates margins on new (draft) orders.
