Feature Request - Pre-record function

The Pearl continues to improve with each firmware upgrade. What would be the possibility of adding a pre-record function? We wheel over Pearls to record events in various locations and often an MC will surprise us by starting the event without giving the agreed-upon cue, so our recordings miss that crucial “Thank you all for coming!” Most professional camcorders have a pre-record buffer that gets tacked onto the beginning of a recording once you hit “record.” Would love love love to see this feature included on the Pearl.
