Add more QuantityCodes

[m4Viper]

Hello everybody - thank you for your great work!

Is it possible to add more usual QuantityCodes to be more flexible? I think some standard and often used codes for "invoicing" are still missing.
for example:
price per ten: TP
price per hundred: CEN
...

Or is their a easy way to add/use codes without building the code on my own?

The quantity code list contains more than 2,000 quantity codes. That is too much for such a component.
