A Recurrent Problem (calendarios)

Use Case:

Create a recurrent series of events in SF.
For a created series, it needs to be able to be changed on a go forward basis only
     - AssignedToID
     - Day of Week
     - Time of day
For a created series, it needs to be able to be deleted on a go forward basis only
For a created series, it needs to be able to change AssignedTo on a go forward basis only


Complicating Factors:

Updating the RecurrenceActivityID record updates ALL events in the series
Deleting the RecurrenceActivityID record deletes ALL events in the series (if performed via API)
Visual Workflow doesn’t play well with DateTime input fields



I thought I would consult the ninjas before charging through with the following rough workaround:

Part 1 - Create a Flow for creating new recurring events
Part 2 - Create a Flow for deleting series (with same RecurrenceActivityID and ActivityDate in future)
Part 3 - String together the flows as follows:

Create series (obvious) - use the flow from Part 1
Change series - use part 2 to delete all future events in a series and then implement the flow from part 1 to create a new series


This solution feels a little labor intensive - Skuid has made me lazy. 

So, do the Ninjas have any advice on how I may be over thinking this problem?
