Google Product Reviews Feed

[JulieAndrus]

Does anyone submit a feed of product reviews to their Google Merchant Center account? (This will allow product reviews/ratings to appear on Google Shopping product listings.)
I see that you can export the Product Reviews to a spreadsheet, but it doesn't contain fields for the product name or GTIN -- these are two basic requirements for the google product feed. How can I create a feed for product reviews?

Are you using a Core Template? If so, the reviews are embedded in your site.

Thanks. I am using a Core Template. I'm a little confused because the instructions I received from Google support say to do this to enable Product Ratings:

1. Sign in to your Merchant Center and click on Product Reviews to register a new feed
2. Provide basic information about your Product Ratings Feed
3. Choose whether feeds will be uploaded manually or schedule a fetch for automatic uploads
4. Provide further details in regard to the feed upload.

So I see the reviews when I use the Structured Data Testing Tool but how can I create a feed from it?
