[Koha] Complex Issuing Rules

Hi everyone, I'm implementing Koha for a large university library that has complex issuing and fining rules, for example, if a patron doesn't return a book within two weeks, he/she is charged KShs. 1.00 per day for the first 10 days and KShs. 2.00 everyday thereafter, the book is marked as lost after 90 days and if the patron doesn't pay up or return the book, he/she is barred from using the library. Has anyone written generic code to handle such a problem? Thanks, Miano Njoka JKUAT, Juja, Kenya.
