On the Advanced Release Burndown report is there a way to make the projection lines extend to the x-axis?

 We've started using the Advanced Release Burndown report on RTC Release 5.0.  Is there a way to configure the report so that the projection lines extend past the verticle line for the end date down to the x-axis?  With the way we're currently configured, the end date is always the last iteration that I select to include in the plan.  So if I add additional iterations past our planned for end date to try and get the projected lines to extend to the x-axis then the end shown is incorrect.
