Need firmware change to give us an option to embed date-time watermark into video

Is there any change of getting a firmware mod to turn on date-time watermark in VIDEO?For both practical and legal considerations it is higholy desirable to have a minor firmware mod for the peephole video cams (and other models) that will give us the user option to enable an embedded date-time watermark **directly** into the imagery data (at a location we desire - e.g. top, bottom , left, right etc.)? For legal reasons the police etc. need proof of date-time in the downloaded and saved video so that they know its not edited and shows actual time clock. It's also just practical for us subscribers to see the date/time DIRECTLY in the imagery wihout having to run the app and computing in from the base date in the app + the time offset counter. Really really would be useful and super easy to do. Please do it for us. I don't want to have to turn over my app to anyone in order for them to derive the imagery date-time stamps from app info. I want to be able to copy it out to a file and have it all contained as part of the imagery. Just found out that I can do an ackward 2-step process to share a link to myself in email then save video from ring site as mp3 and the date-time is overlayed at lower right. Would be nice to have all video this way online and in the app data to see daate-time clocking frame by frame. It's hard to correlate events to time with time tagging like "1 hr 20 mins ago" etc. in the summary screen. Thanks - and great product by the way.
