Global Calendar Events

I would like it to be possible to add events into the calendar that are visible to all users (including students) without inviting them.

For example we have term breaks which apply to all students and staff. I can create an event that all 'system users' can see, but this does not appear when viewed from the students' perspective. I can invite students into the event, however it would be incredibly tedious to be constantly updating these calendar entries to include the new students we enrol each term.

Similarly we could enter the public holidays applying to the states we train in, so students are aware.

An additional thing is that the student calendar displays Sunday - Saturday, and the system user calendar displays Monday - Sunday. It is not really a problem as such, but it would be nice for them to be consistent.
