Please add advanced pre record for older wired devices

Hi- I want to make a feature suggestion for users of the video doorbell 2 when it is hardwired. Please add the ability to pre-record 15 seconds prior to a recorded event. Many professional level recording systems have this feature and I have several motion events where much of the event happened before the trigger but is lost because you don’t allow pre-recording on the hard wired video doorbell 2.
