Add feature to adjust fasting time, instead of only 2 days TODAY AND PREVIOUS DAY like now

I have difficulty adjusting the fasting time, there are 2 possible cases:

1. I cannot adjust the fasting time if its duration is not in TODAY and PREVIOUS DAY, which means I have to go into the app every day and MUST NOT FORGET to adjust it in the appropriate time period, which means I cannot plan a fasting in the future that has a duration longer than 2 days.

2. I also cannot adjust the fasting time of any other day in the past; if I forget to edit, there is no other way.

You guys have done a great job adjusting for all days, including previous or future days for meals, dishes, activities, water,... in Diary and I really hope you can do the same with the Fasting feature. Thank you very much!
