Is it Possible to Dynamically Populate Prepare e-mail in "Send Email on Update" rule?

Summary:

In creating a rule that is "Send Email on Update" there is an option to select all the Reviewers but no option to select preparer. I can put the prepare e-mail directly in the email address but that means creating this rule specifically for each reconciliation and manually putting in the preparer to each one. Is it possible to dynamically populate the preparer to receive e-mails on updates?
