Meeting Update and Cancellation Notes Prompt

I would like to suggest a feature where, when I update meeting details—like changing the time—and send an update, a small window prompt appears so I can include a brief message, such as "Please note I updated the meeting" or "We changed the time because so-and-so couldn't make it." I'd also appreciate the same option when canceling a meeting, where just before confirming the cancellation, I can add a short note explaining the reason. This feature already exists in Outlook and other scheduling tools, so it would be great to implement something similar without reinventing the wheel.
