Increased number of debt letters / reminders

Feature requested
What feature would you like to see in QuickFile?

I would like to see additional letters be added to the debt reminder process. Currently there are 3 but having letters 4 and 5 would save hundreds of pounds per month to my organisation.

Typical use case
How would this feature be used?

In the same capacity as with debt reminders 1-3.
