Google Shopping GTIN/UPC/MPN - Shopsite Advanced Options SKU

[anthonyd]

Hello,
Is there a way to map the advanced options sku field to the Google Shopping GTIN/UPC/MPN field. Currently, this can only be mapped at the product parent level and not for each variant (size,color,etc).
Thanks,
Anthony

I could not find a way to get the advanced option sku to display in a feed.
