Distributions of HR / Power in 'Totals' view

For workouts, we have this interesting views that show the (discretized) distribution of Power / HR throughout an activity:


Could it be possible also to add something similar to the totals, so we can see the same over a longer time span?

So, rather than just group them by Zones (which are usually 5-7) use a lot more (at least 15-20) bins?

Basically what I’m interested is is to see the distribution of my heart rate / power (from https://twitter.com/nntaleb/status/1577978418792128513/photo/1).

Using Zones kinda does the trick but due to the low amount of zone the approximation / discretization is huge, especially for the most interesting part (Z1, which takes usually the majority of time)
