Multiple Currencies via WP All Import

Hi,

Great plugin.. thanks.

I have a store which imports once-off products (rare, second-hand books) using WP All Import via .csv on a daily basis. The owners need to be able to set individual prices per-product in multiple currencies.

But these fields do not show up in WP All import as far i can tell. Where and how is the data stored? WP All Import does allow for custom fields, and even custom functions.

Many thanks,
Simon
