Payables Import changing item and tax amount in distributions

I am trying to import invoices with multiple lines with some lines that have taxes already calculated.  In order to get them to import I am following the use case below:

Column               Line 1          Line 2          Line 3          Line 4

Line Type              ITEM               ITEM          TAX          TAX

Amount               100               50                    10               5

Line Group          1                    2               1                    2

Prorate               Y                    Y                    Y               Y

Tax Regime                                                  A               A

Tax                                                                 B               B

Tax Status                                                       C               C

Tax Rate                                                       D               D

But it is creating distributions like below:

Line 1     Dist 1     Item                              95

Line 1     Dist 2     Recoverable Tax          15

Line 2     Dist 1     Item                              47

Line 2     Dist 2     Recoverable Tax          3

How do I get the import to keep the amounts in the distributions as entered in the interface table and not change them?
