Splits with power data

It would be super helpful to be able to view splits with power data.
For instance:

Working on max sprints
lap1/ power 1s /15s /30s
lap2 /power 1s/ 15s/ 30s

Working on a 20 min climb
lap1/ time/ avg power /30s low and high power avg/avg hr
lap2/ time/ avg power /30s low and high power avg/avg hr
lap3/ time/ avg power /30s low and high power avg/avg hr

It could be customized and highlight low/high splits

Currently you can't even look at the max power for your last lap. Seems like something that should be basic functionality.
