[Koha] flat fee on notice generation

[Radek Šiman]

Hello everyone,

I'd like to ask a question concerning overdue fees. One of our library 
requests to add a flat fee to common overdue fines. Is it possible to 
automatically generate a flat fee for the 1st, 2nd and 3rd overdue 
notices? Let's say a patron owes $5 as a overdue fine of 5 books. The 
library needs to automatically add to it, for instance, one-off $10 as a 
flat fee, because the patron has been notified about the items over due.

Of course, it's always possible to add such a fee manually, but then the 
staff has to know which kind of notice has already been generated and 
the amout must be calculated by humans not mentioning that people can 
make mistakes.

Could anybody recommend a good solution or is it a missing feature right 
now?

Thanks a lot,
Radek
