Supplemental-feed controls appear alongside Merchant Center automatic import

What changed

Emmanuel Flossie shared a Merchant Center screenshot showing that a supplemental feed could be added alongside a primary source based on Google's automatic import. His post is careful about the timing: he had not seen the combination before, but says it may have been available for much longer. That distinction is part of the update, rather than a reason to invent a release date.

The practical question is whether an automatically collected product catalogue can be supported by an additional, maintained data source in the account a merchant actually uses. An observed interface can help a team find a configuration worth checking. It does not establish that every account has identical source options, or that adding a file will automatically repair every product attribute.

Before making a change, document which source currently owns the catalogue and how product identifiers are generated. Check a small sample of items against the website and the supplemental data. If the sources do not refer to the same products consistently, the team can mistake an unmatched row for a successful update. Keep the intended attribute changes explicit so the result can be checked after processing.

Responsibility for maintenance matters as much as availability. Someone needs to update the supplemental source when the underlying product information changes, and to investigate conflicts or processing errors. An extra source should make an existing workflow clearer; it should not become a second, forgotten representation of prices, availability or product identity.

Treat this as a configuration to evaluate in the current Merchant Center interface. Save the original settings, make a bounded change and inspect the resulting product records before extending it across the catalogue. Do not infer eligibility for every account or a new platform-wide release from one screenshot. The source post and image were checked for the Week 37 reconciliation on 14 September 2026; that reporting date does not identify when Google first introduced the option.

Why it matters for advertisers

Emmanuel Flossie observed supplemental-feed controls when the primary Merchant Center source used Google's automatic import. He explicitly notes that the option may have existed for longer, so this is a workflow observation rather than a dated launch.
