Unit cost based on Purchase currency and current rate

We would like to have a feature where SI will update the unit cost based on currency cost, purchase currency and current currency rate. We sell almost everything in local currency (NOK) but often buy from distributors or mfgrs in EUR, USD, GBP, DKK or SEK. Since volatile currencies like ours fluctuate a lot, it would be a huge time saver if we could do an excel (CSV) price list import from i.e. Extron, have the purchase cost updated to the correct field and be assured that the unit cost will be correct.

There should also be an automated currency rate update feature. Check box - update daily.
