Extend macro targets functionality
I'd love to be able to use the functionality of the "keto" macro target setting (where the daily fat target changes according to the calories burned) for carbs instead, maybe by providing a function to lock individual macros in the fixed or ratios settings. My goal with this is to lock my daily protein to 120g and my daily fat to 100g, and automatically adapt the carb target according to the calories burned of the day.
This would be a valuable addition for (non-keto) endurance athletes, where the burned daily calories can vary by 1000kcal or more, and during a training cycle I'd like to make those additional calories up with fruits and oats etc. rather than fats and proteins.
