Can ARC calculate a value in currency on a loaded source balance?

Summary:

Hi

Thank you for all previous support on questions and issues.

Question of the day:
Can ARC calculate a value in currency on a loaded source balance?
Example: I am loading GL balances from Oracle Fusion ERP in local currency NOK or SEK, but would also like to see the balance on some accounts in reporting currency USD.
Is this possible by calculation or does balances in other currencies need to be loaded as well?
If ARC can calculate, how do I need to set up my profiles?
(We are loading currency rates each month)
Thank you in advance
