You are essentially asking FDS to track daily usage. You won’t going to get credited days of the month back. If you purchased the monthly plan you are more than welcome to cancel your recurring and re-enable it when you are ready. But trying to get down to daily account credits is near impossible.
Its the same logic as “I was traveling and couldnt fly for today”. You will not get that time back. That is the whole point of the grading system. I am a grade 3 because I have been busy with work and have not been able to keep up my landings.
The same logic holds true for my cable bill. If I don’t watch TV today, I am still charged the same each month.
