Average power as a function of time

Hi there!

I would like to have the possibility of seing my average power so far at any time in a ride, especially after a ride.
After a ride I can see Power, Speed, Heart rate and Cadence, What I miss is having the possibility of dragging along the timeline to see my average power so far, say 10 min into the ride.

The same would be nice for
average speed so far
average heart rate so far

I love Zwift, ride on!
