If this has been addressed, I must not have found the proper keyword - apologies.

With a recurring event, is there a way to edit the occurrence of future events without changing the past events? I have a group that meets X number of times per week. They meet more often in the spring and summer, and fewer times in the fall and winter. When I make the change to the event now, it applies that change to the entire history. The time and place are the same, it's just the seasonal frequency that is the variable.
