Create customer via service classes / set Dimensions

Hi,

I am creating a customer via AIF service classes.

I managed to get it working just fine with usage of few classes:

CustCustomerService                     customerService;
CustCustomer                            customer;
CustCustomer_CustTable                  customerTable;
CustCustomer_DirParty_DirOrganization   customerDirParty;
CustCustomer_DirPartyPostalAddressView  customerAddress;
AfStronglyTypedDataContainerList        customerContacts;
CustCustomer_DirPartyContactInfoView    customerContactEmail;
CustCustomer_DirPartyContactInfoView    customerContactPhone;

Now the tricky bit: I need to set the DefaultDimension field - I know that I should probably use the AifDimensionAttributeValueSettogether AifDimensionAttributeValue  classes, but I happen to have the RecID of the default dimension (DimensionAttributeValueSet table record)

Any ideas whether it's possible to simply  set this RecID field instead of re-inventing the wheel ?

Thanks,

M
