Workout guidance

I'm a new user. I only do spin training and only use a heart rate sensor, no power or cadence sensors.

I expected that the interval timer would give me numerical guidance per my custom zones, rather than just telling me "sub-LT" and making me remember what my numbers are for that zone and concentrate on getting there.

Am I missing something? Does the app already do what I want? If it doesn't, is it in the plan for it to do that soon?

My requested feature is that you populate your blank HR intensity field - in the right column next to the sensor HR- with my personal numerical target HR range for that intensity, which zone numbers I could either enter manually or the app could calculate from my thresholds or from whatever else you wanted to use as input, though for liability reasons I imagine you'd rather the user just entered numbers... that's what I want to do anyway.

Taking it to the next level would be voice announcing current sensor numbers vs my target numbers - at some helpful intervals - so that I could exercise to target numbers without having to stare at a display.

Thanks.
