Distinguish appointments on mobile app by Category

When looking at appointments on the calendar, as well as when initially clicking on the appointment and arriving on the screen with the snippet of the Appointment Details, there should be a way to have an indication as to what the "Category" of appointment it is

The reason I ask is because we use the "Category" to distinguish whether the appointment is a "Sales Appointment" requiring a full demo, a "Write-Up" that's simply a contract signing appointment, a "Re-Visit," etc. The old app showed that upfront so that sales rep could know at a glance what their appointments entailed. Their initial list of appointments for a given day would show a small colored box that distinguished a category of one appt from another, as well as the Subject line being visible that might have Sales Appointment or Write-Up inputted. 

But now to find that out you have to dig deep and click into the appointment details and scroll down to find the obscure field of Appointment Type.
