How do we know who cancelled an interview?

Summary:

Unable to see if it was a manager or the candidate who cancelled an interview.

Content (required):

We want to be able to track if it was a candidate or a hiring manager who cancelled an upcoming interview, however if either cancel it just removes the entire interview entry from the candidate record. We would hope it would update to cancelled and give an indication as to who performed the cancellation
