Advanced training workout

I have an idea of updating the training manager. When I now build interval training (dsitance or time intervals) it can just give me voice feedback of set variables after each interval.

I would like to have possibility to add/set up the target value (min-max) of variable within the interval.

Example of what I mean:

Interval 1

-Interval duration (distance or time) . Example -5 min

-Variable tagret min - max. Example - HR80%-HR90%

Interval 2

-Interval duration (distance or time) . Example -1000m

-Variable tagret min - max. Example - Cadence 80 - 100

atc.....

You could be able to start the training with track recording and training intervals with target values are visible on the screen.

Thank you.
