When this workflow arrives, it will do what the others do: collect the documents where they are needed, put the questions so your clients answer them themselves, and name the document behind every value the AI reads. It is not built yet.
This workflow does not exist yet. That is why there are no figures, no sections and no try-it button here — only the invitation to tell us you need it. That is what decides the order.
