Bulk-modify only future events of a recurring calendar event (i.e. "archive"/"freeze" past events).
It is helpful to have a record of past events/meeting as they happened.
Currently, modifying a recurring event (e.g. moving a team meeting from Tuesdays to Thursdays) will change all occurrences, past and future, which means the record of previous events is lost/not accurate.
When modifying a recurring event, users usually want to implement a change "from now on", so at the very least they should be given the option to modify (a) single event, (b) future occurrences, (c) all occurrences.
See Google calendar for implementation.

This feature should have been added long ago ... what's the delay?
Can you please re-add the feature to edit or change future occurances in a series without deleteing the past occurrences?
Create the option to change a recurring calendar appointment series in the future only. Or to not impact modified dates within the series.
