Set different values for Invoices Due After (Days)

It would be great (and i think it makes sense for a lot of people) if there was a way to define, for every client, a different value for “Invoices Due After (Days)” but still keep a default general value.
This way we could override, on a client basis, the default value. Sometimes there are different payment deadlines for different clients or projects.

Thank you for this excellent piece of software.
