Summarize Account Distribution lines into Fixed Assets thru Mass Additions

When we run the Mass Additions report to transfer the appropriate invoice transaction lines and distribution lines that relate to Fixed Assets we are getting multiple lines due to the way R12 is handling tax when using a third party vendor for tax purposes.  Is there a way to summarize the lines so that only one distribution line per invoice transaction line comes over.  Currently we are getting each individual distribution line which means that the Mass Addition report could be up to 30 pages long depending on the type of invoices that are coming over.
