Comparing total time spent with custom timeframes

Hello,
Back to the 2020 I proposed that it would be possible to have a table (a bit like in totals) to compare time spent in one sport or in zones from one timeframe to another.

I like to compare the volume or time spent in Z5 in the 3 months timeframe before a race for example. I know that there is the graph tab, also I could put two browser windows side to side but I find it a bit cumbersome (I also mainly use my phone)

So I bring back this old idea… thank you @david
