Capital Events - Reverse Capitalization

Hi,

    I'm trying the following scenario to understand the concept of reverse capitalization in projects.

1) Define an CIP asset in projects

2) Enter two capitalizable expenditure items

3) Enter a capital event and associate cost(two expenditure items)

4) Generate asset lines and interface asset lines to FA

5) In the capital events screen, click the button "Reverse" to reverse the event & asset because only one expenditure item should be associated to the event.

When i execute the generate asset lines process, it's generating the reverse entry and a positive entry with the two expenditure items.

This way i'm not able to exclude an expenditure item from the event. Is there a way to create just the reversing entries?
