Copy and Paste calendar entries from one month to another

I have a calendar that tracks PCI review dates. It would be nice to copy and paste one calendar entry to another month (e.g. The calendar entry for one review could be copied and pasted three (3) months later when the next quarterly review is due). This would help eliminate re-entering each entry for every quarter.

Another option would be to add a repeat quarterly and semi-annually option to the repeat menu. The only problem that I have with this is that there is no option to specify to repeat quarterly and, if next quarter's date falls on a weekend, rounds to the closest business date.

If you have any questions or if you need additional information, please let me know.
