Currency property to show in deal currency rather than company currency

[KatAddison]

We have multiple revenue fields on our deals (deposit amount, balance remaining, etc) and also operate in multiple currencies

While i can display deal amount in the correct currency for the deal. If i format the other revenue fields as a currency it is only displayed in the company currency, which obviously doesn't make sense on the deal. 

Should be an option to have the revenue in the deal currency
