SSRS: Can I make a rectangle that truly hides

I have a report at the bottom of which has an optional section.  This optional section is entirely contained in a rectangle.  My problem is, when I set this rectangle's hidden property to true, it is hidden but there is still whitespace added to the end of the report (where the rectangle would be).  I don't want to create a sub report if avoidable, is there anything I can do to get it all the way hidden?

I'm attaching a screenshot of the designer with the rectangle selected as well as a sample output of the report with data.

Thanks!
