Would like an icon on the schedule indicating if a patient has a copay

Currently, the $ on the schedule indicates if the patient has a balance due, but I would like an icon on the schedule that notifies if the patient has a copay associated with their account (basically if there is something written in the "copay" box under the insurance section). This would be useful because I have a hard time remembering which patients have copays, and working as the only front office in a very busy clinic I do not always notice the pop-up box that appears when a copay is due, especially if the provider is the one to check-in the patient.
