Support Regex matches in calendar groups

Feature Request -

Would like a way to specify regex matches for calendar items.  The regex for the calendar group would be dynamically applied when the event is evaluated.

This would allow a single calendar to provide more flow control to FreePBX.

For example, a work schedule calendar could have events called "lunch", "open", "holiday" to provide more appropriate messaging.  Or an office could have a call schedule for doctors, IT support, etc.

I found the specific events functionality, but that requires someone to login to the admin panel and re-select items when the calendar changes or events are added.  That is not easy to train a receptionist to do.
