Feature Request: Calorie Burn Rate Per Lap

I find the calorie burn rate field extremely useful to gauge my ability to hold an intensity level during an endurance event. For example, even though I might be feeling fine early on, if I look down and see that my burn rate is 1,000 I can very easily determine my ability to sustain that rate for the event duration and make a decision about whether and when to take the intensity level down a notch.

Given that I've found having this information so useful, I really want it for interval training as well. I think it would be almost trivial to provide Calorie Burn Rate Per Lap. How about it?

Bonus points for Kj's per hour and Kj's per lap.

Thanks!
