This piggybacks on enhancement requests for using Groups in Automated Workflows.
Our Marketing and Communications team has a form for employees to submit requests for the marketing material design (e.g., a flyer for an upcoming event). Proofs are uploaded to the request and the same group of people need to review and annotate before sending back to the requestor/sending to the printer. Inviting individuals within the group to review proofs would be very helpful. I know you can create a column for that, but if it's the same people for every item submitted, it would be easier to maintain, especially as someone joins or leaves the review team.
