Provision for incremental fine is needed in Circulation and Fine Rules.
For example, for first 10 days charge $1 per day, from 11th day charge should be $2.

So far no one has written any code to do this, so someone either needs to find it interesting enough to spend their own time on it, or someone needs to pay someone to write it.
