Battery Date

I like the EventWatcher “Batteries” tab, but I have some devices that just stop responding. The worst offenders are Everspring Motion Detectors - they may show 70% battery one day, and then the next day are dead and stop responding completely until you replace the batteries. I have a PLEG that pulls battery date and alerts if they have gone 24 hours without an update. My question is - can the “Batteries” tab be enhanced to show not only the most recent battery level reading - but also the date of that reading?
