Parents Request Make Up Class

I find myself constantly being drowned by parents contacting me about makeup classes. I would love a feature where parents can request a makeup class on their own which can be approved by me. The set up could look identical to how it is set up for us on our end: they select the absence they wish to make up, select the class and the date for the make up, and send the request to me, where I would approve or deny it. This would be a big time saver!
