Interview availability - sync it for all interviewers and include calendar invites

We've not really managed to get interviewers into habit of adding their availability to Networx, so our recruitment team have to do this. But they have to do it individually for each interviewer, which is time-consuming. It would be great if could have feature to do it for selected interviewers at same time.

And then it would be good if a email / calendar notification could go to interviewers to protect that time in their calendars.
