There has been a number of people that have pointed out that the inability to use HRM as a data field on the custom screens is a significant limitation. Can someone from Garmin please comment and let us know whether to expect this in an update or not? This is a big deal to me; probably a deal breaker, and it seems to be a big deal to others. It's a safety issue. We shouldn't be changing screens while rolling and the ability to choose any combination of data on the custom screens is the way to do this. Garmin, please comment.
