We sell kidswear, so must submit an age group of newborn, infant, toddler or kids for each product on Google Shopping. However, a lot of our products have enough different sizes that they fit all four categories.
Despite the Google Shopping app submitting product variations as individual listings, the age_group field information is given at product level, so each product can only have one age group specified, which means our ads won't be served in the most appropriate way.
It'd probably be possible to submit this information at variation level via a .csv upload, but will that create conflicting product information in Merchant Centre, and is a lot of additional processing work.
Does anyone know of a way to manage this with the app, or a suitable hack?
