2 aims interval training in cycling- Edge 820

- is there any possibility to plan training with 2 aims ? I.E. in most cycling plans we can find intervals : go Zone 4 (Pwr /hr) with cadence 110+ :

or go in zone 2 every 3 minutes for 15 sec cadence 120+.... this it easy in most cases but when you are doing few intervals in highest zone and you have problem with breathing and salt is your eyes.....remember of any additional numbers is not easy :)


is it possible to plan, and/OR  get live information about both desired values during training ? When power/hr is out of zone - some blink , and when cadence is to low - some reminder / color /pointer ( of current and desired value - for each interval separately

- is it possible at all or I have always remember one parameter ? 


Garmin - is it really difficult to introduce it in 21th century :) ?
