Editing recurring bookings

Hi! I’m really enjoying Scritches so far, but I don’t see a way to change specific weeks for recurring bookings. What if a client normally has scheduled walks at 9:00 AM every Monday and Wednesday, but for just one week they need to change it to 3:00 PM, or change the days to Thursday and Friday, before going back to their regular schedule the next week? If there is a way to do this already other than cancelling the walks that week and setting up a one time booking, please let me know. Thanks!
