Can Garmin Connect merge the data of 2 devices

I have been using the Forerunner 955 Solar for a while now and I am pretty happy with it. For daily wear, I would like to have a smaller tracker for sleep/hrv/steps etc. Something like a vivosmart device. Is Garmin Connect capable of merging the data of both of those devices to generate a unified body battery/training status/steps/etc. status, or will it only do that for one of the devices at a time?
