Syncing a common field between language-specific documents in Sanity

Is it possible to sync a field between two documents? I started with the ambition to use object translations, but realized that all fields expect one are unique to each language. The common field is an array of images that would be nice to keep in sync between the documents.

I would recommend you hide that field on other language documents, and make only one document’s version of that field the single source of truth.
Then in your queries, query for that field from
that document.

That makes sense! Maybe a notice field that lets the editor know that the field is available on the base language only.
