I an trying to have folks select from many files at the end of a survey from a multi-select question, and then email links to the files selected. The best I have come up with is:

1. Add the Qualtrics file identifier number as a recode value
2. Branch based on number of files chosen (up to 10)
3. Set embedded data fields for each answer
4. Send the email with the embedded data fields with unique file ids amongst 10 email templates in urls to provide only the files selected.

Is there a better/cleaner less human error prone way of managing this?
