Currently using the CS300

I login to and drill down on a particular exercise data set. Unfortunately the only zone data being captured is Zone 1. Zone 1 currently is set between 43% HRM and 86% HRM.

2 Questions.

1) Is there a way to modify what the range for zone 1 is?
2) Is there a way to add additional zones?

Ideally I'd like to see data caputured for zones 1-5. Then when I view the HR Zone tab, I get a break down graph of time spent in each zone. Showing me one zone with such a broad range, isn't very helpful
