AbleCommerce Shopping Cart Software

Hi folks,

I have a big problem.

I'm working in Payment Methods page and I need add new items in DropDownList named PaymentInstrumentList (Label Type on page), but I saw that it is filled by a enum called PaymentInstrument and there are 16 items below:

Unknown = 0,
Visa = 1,
MasterCard = 2,
Discover = 3,
AmericanExpress = 4,
JCB = 5,
Maestro = 6,
PayPal = 7,
PurchaseOrder = 8,
Check = 9,
Mail = 10,
GoogleCheckout = 11,
GiftCertificate = 12,
PhoneCall = 13,
SwitchSolo = 14,
VisaDebit = 15,
DinersClub = 16

and here in Brazil we use more those below:

HIPERCARD, SOROCRED, AURA, BOLETO BANCÁRIO ***, ABN REAL, BANCO DO BRASIL, BANRISUL, BRADESCO, HSBC, ITAU SHOPLINE, UNIBANCO

So, by I know I can't change this enum, can I?

How can I solve this problem? Because to remove, it's simple! I just ignore, but for me add....I don't know!

Help me!

Salton.
