It would be very useful to use different currencies in Trackvia so it would automatically calculate the value in USD based on daily updates.
We deal with international suppliers and many of our deals are in local currency.
The addition of foreign currencies to format both currency and calculated currencies is on our roadmap for future implementation, however we do not have a timeline as to when this will be available. We'll update this post with any updates!
Having said that, the integration to other sites to automatically update exchange rates is potentially possible using the TrackVia API and any exchange rate software that also has an API. This would be a rather complex level of integration that we are not familiar with.
