Hey Joseph,  
That would be a great feature to add indeed, looking forward to it!  
As I mentioned earlier, I’ve modified the Pitch in a Group with the use of a Snapshot and then I’ve put that snapshot on the Parameter Track inside my event and everything works as expected, pitch shifting sound but also changing the duration of the event.  
Cheers
