ZC v1.5.0, minimal add-ons.

I'm putting together another store that has some products that are priced in USD and others that are priced in another currency (CRC, Costa Rican Colone). Is there a way to specify this in the ZC admin and to have the USD price 'converted' in each session?

Converting the price one time (at product creation) doesn't really work since the CRC fluctuates significantly.
