There is a secondary HR add on IQ App... would imagine there is a similar for Power. Lots of people use multi power meters for indoor virtual bike races as a way to help validate readings to prevent cheating.

Here is one that should work: ANT+ Power Meter - https://apps.garmin.com/us-EN/apps/70f1aea3-f1d3-47f6-b7aa-23f029a75e3b#0

Also if using Zwift... can record on garmin with one, zwift on the other meter... then use ZwiftPower or DC Analyzer to compare the two activities
