Identify and track calls in Service for Vehicle Status "is my car done yet"

When a caller contacts the Service department to see if their vehicle is done being serviced and they can come to pick it up - those calls are referred to as Status Check calls. As a Service Manager I would like to know how many Status Check calls I get (day, week, month) vs. true appointment opportunity calls. Lets say I had 1500 calls into Service this month and 500 of those were Status Checks, then I would know 1/3 of my volume is callers finding out if their vehicle is done and I would know my team is not making their outbound status update calls. Then next month I have 1500 calls but now Status check calls are 750. I know my team is doing worse this month making outbound status update calls.
