Interchange Receiver ID on ACH file with CTX format

We are using R04572T2 to create ACH files with a CTX format.  This format includes EDI 820 information in the ACH file.

The ISA 08 element of the EDI information is the Interchange Receiver ID.  My understanding is that this is where we should identify receiver of the payment using the ID that is supplied by the receiver of the EDI information while we identify ourselves using the Interchange Sender ID in the ISA 06 element.

The problem we are having is that both the Interchange Receiver ID and the Interchange Sender ID are coming from the F0030T table (Bank Account X12 Information), so the Interchange Receiver ID is not payee-specific.  We have one record in this table, so every ACH payment goes out with the same Interchange Receiver ID.  Is there a way to specify an Interchange Receiver ID for each payee and have it populate the ISA 08 element?
