Create Multiple Receivable Account per Invoice automatically

Hi,

Our system creates thousands of
invoices daily automatically.  We import data in the flat file into
RA_INTERFACE_LINES_ALL then run AutoInvoice Master Program.  Currently,
Invoice lines in one single invovice has the same receivavle account which is
tied to Transaction Type of the invoice.  The new orgnazation change will
require invoice lines having the different receivable accounts within the
same invoice. 

Is it possible to achive this automatically?

Any suggestions/advices are greatly appreciated
