Auto Invoice with Multiple Distribution Lines including tax

Hello,

I am in need of importing invoices with multiple distribution lines(Rev) depending on the service type to go to an account also tax line.  If I only insert to RA_INTERFACE_LINES_ALL it does pickup the transaction type information and processes it. But i will need to override it since these lines will have multiple rev/tax lines(Setup doesn't provide the option? If yes sorry I am not aware of it).  Please share your thoughts.

Thanks
