I chatted with Support today. I asked if there were any plans to add a customized field for the Body Battery so the current BB status could be included in a watch face. The response is that BB was left off on purpose but there was pressure to add BB as a customized field. I would think this would be a no brainer for Garmin given they are including the BB in all the new watches and are touting is as a good indication of your daily stress from sport and general stress.
