Create a purchase order in vendor's currency

Create a purchase order in vendor's currency

I am having a problem working this out and would appreciate some suggestions. We have Books and Inventory working in tandem. We are in Australia, our product is sold in Australia in $A and obviously all our invoices, accounts and reports need to be in $A... so this is our base currency. However our products come from Europe so we need all of of our purchase orders to show the price in Euros. There is no point showing the ordering price as some randomly generated conversion figure - that is meaningless to our supplier, as well as changing daily.

The only suggestion I have found is to set Euros as the base currency and use a price list to set the price of sales in $A. But won't this mean that all reports and accounts will be in Euros? Also, to do this I will have to delete all current transactions and we have been using Zoho for almost a year now.

There must be some other way around this. It seems like a very basic requirement that you should be able to create a purchase order in the vendor's own currency.
