[Koha] Incremental fine in KOHA

[Rupinder Singh]

HI,
Our library has a fine rule that attracts a fine amount of 25 per day for
the first week after the due date.
after the first week, it is 50 per day
and after the second week, it is 75 per day.

The out-of-the-box installation of koha only gives the option to put one
rate of fine for a user category.
How can I configure my koha to have the incremental fine calculation.?
I can tweak some settings, but I am not an expert coder.. please help


thank you
