Set Protein & Fat and variable carbs AND weight changes

I like to plan my daily food intake in terms of:

  • almost fixed protein (1g/pound of total weight) and,
  • almost fixed fat (.3g per pound of lean weight) and
  • variable carbs to fit my daily calorie intake objective, derived from calories burned (+/- weight change).

It would be useful also to have different weight changes options for different date ranges to account for bulking periods (for a months) and cutting periods (for a few weeks).

Finally weight change options could be expanded (e.i. 3/4 pound) for a more granular approach?

Is there a way to do this? or is it a planned development?
Thanks.
