Convert currencies to USD using today's exchange rate

Is it possible in QuickBase to convert different currencies to USD using today's exchange rate?

I have a field where users enter costs in different currencies, but want these costs to be converted to USD so i can compare costs. 

I know i can do that by create another numeric field and set us a formula with another text field contains all the currencies and then identify all the foreign currencies values against USD, but this needs to be updated regularly as the exchange rates change. Any function in QB to resolve this and convert currencies to USD based on today's rate.
