If you use Qualtrics’s email distribution you can include the account name in the distribution list and it’ll be included as embedded data, the only issue here is Qualtrics won’t send identical emails to users in the same distribution so you would need to piple the account name in the email; I would put it in the subject and body.
If you don’t want to use Qualtrics email you can still generate personal links in the Distribution section and send each PM thier personal link, it’ll save you the step of creating the links yourself.
