I'm trying to create a PDF generation automation. I have a number of PDF "concept notes" each of them tied to a particular option I'd like to list in an Airtable form (though open to other form solutions). I would like users to be able to use a multi-select option in the form to select which concept note they would like to be emailed, and have the automation merge all the options they selected into a single PDF, then email that to the user. I'm not sure how to design the automation to search for the docs (in a Google Drive) based on the form responses. How would you go about setting up such an automation? Any feedback or ideas welcome!
