I would like the ability to use different units within the session and have it integrated into the workout builder.
You can only work with one unit (%threshold pace, %threshold hr, %maximum hr...) in the workout builder, and it would be very useful to be able to combine at least two units.
For example, warm-up in RPE and active in % maximum heart rate, or also to be able to indicate (in two steps) a step in one unit and the recovery in another unit, for example, sets in %ftp and recoveries in RPE.
