Avoiding non recoverable tax line from Mass addition Create program for leasing

Hi Friends

I have a requirement where invoices for  leasing should be capitalized without merging the non recoverable tax line to item line whereas if I have an invoice for assets then mass addition should capitalize the  value of asset after merging non recoverable tax line to item cost.

We can identify the leasing transactions and Assets transaction with separate account code combinations. We are on R12.1.3 .

Any help is much appreciated.

Thanks
