Measurement depending on training type

I would like to run my Z2/endurance/easy runs on LTHR, and intervals on pace (or power for the matter). Feature request: have a number of training types (ideas):

• recovery

• easy/endurance

• tempo

• threshold

• vo2max

• interval

Then make it possible to select a measurement type for that training type:

• LTHR

• Pace

• Power
