Paying Vendors overseas via ACH ???

Hi-

We are attempting to do this following:

We want to be able to use ACHs to pay vendors in Australia/New Zealand using our HSBC account (our account is also in Australia, although the bank, HSBC, has many US Branches)

Unfortunately Coastal does not support payments going to Australian accounts. Therefore, it appears that we can manually enter the ACH information into the HSBC website and make the transfers in that manner.

My question is-- how would we add "Outside ACH" as an outgoing payment type  and use it in Netsuite (that is to say, when going to "pay bills", Netsuite always wants to print checks)...
