Accept & Do Not Send a Response

This is a critical issue for me in my role at work. I do event planning and send building wide outlook calendar requests to 240 people on a regular basis.  I have found that people assume that the "accept but do not send response" records your acceptance for the sender but simply avoids sending an email. I do not want to read through 240 emails, but I do need to see how many people have accepted or declined.  None of us want unnecessary emails in our inbox.  It seems to me that any actions within the accept, decline, or tentative categories need to filter back and be recorded in the sender's tracking view.
