it would be nice, if it is possible to add Fat/Carbohydrate- and of course the overall energy Combustion data from a lab test (e.g. Inscyd, Spiro) to the training zones. So it would be possible to automatically calculate e.g. the fat/carbohydrate combustion during a training session/training week. I think, that would be a great improvement For all coaches, who use those lab tests. Other Platforms (todays plans, azum) already have this feature...
