I want to have a user-input field where the coordinator can choose what people from her group to receive a daily report. Currently the closest choices in the subscription delivery only lets me choose by role or manually inputting an email. Are there any other ways of getting a subscription to send to a user-input field?
You only option is to elevate certain users to basic Access with Sharing. Then make a Role called people who receive the XYZ report. That Role should have no permissions to see or do anything. Then your specials user can A and remove users to that Role.
