Merchant Center Price Mismatch

Hello

I have a store located in Australia with base currency of AUD. I am using a GEO-IP currency switcher to set automatically change to local currency of visitors.

This presents a problem with the Merchant Center product feeds when Google crawl my site and, since they are in the US, the currency suggests my site is USD, but the feed is set to AUD.

Is it possible to add ?aelia_cs_currency=AUD to the URL in the feed. This will ensure when Google bots crawl my site, they still see currency in AUD.

Thanks in advance
